Although raw materials are very limited in Switzerland, the country has a world-class manufacturing economy fabricating raw material imports into high-value added exports. The engineering industry, together with metals and electronics, employs about 9 percent of the country's workforce and contributes around 40 percent to Swiss export revenues. Leading areas in the sector include precision engineering, in particular the world-renowned Swiss clocks and watches (accounting for 8 percent of export revenues in the early 1990s); scientific instruments; heavy engineering and machine building, including specialized, custom-built equipment such as generators and turbines; food products, particularly specialized luxury goods such as chocolate and cheese; textiles; chemicals; quality pharmaceuticals; and fine handicrafts.
Were any German V2 rockets shot down by Allied aircraft in World War 2?
- on February 14, 1945, a No. 602 Squadron RAF Spitfire wingman fired at a V-2 just after launch
- on October 29, 1944, Lieutenants Donald A. Schultz and Charles M. Crane in a P-38 Lightning attempted to photograph a launched V-2 above the trees near the River Rhine,
- on January 1, 1945, a 4th Fighter Group pilot observed a Big Ben "act up for firing near Lochem ... the rocket was immediately tilted from 85 deg. to 30 deg",
- a B-24 Liberator of the 34th Bombardment Group over the Low Countries at ~10,000 feet saw a rocket climb through the formation like "a telephone pole with fire squirting from out of its tail. ...a left waist gunner in our squadron let fly a burst and down it went". The unit painted a V-2 on the B-24 such as one would mark a downed enemy aircraft.
Can any plane turn or rotate at an angle of 90 degrees and keep flying?
Any plane can make a 90 degree turn on the z axis and keep flying.
What is out of plane bending in beams?
If the beam bends such that the plane of the loading is parallel to axis of the beam passing through its center of gravity then the bending is known as in-plane bending. Otherwise due to effects of twisting and lateral forces perpendicular to the plane of loading then it is called out-of-plane bending

How much percentage required in 12 to get admission in aeronautical engineering A?
The wingtip vortex, which rotates around from below the wing, strikes the cambered surface of the winglet, generating a force that angles inward and slightly forward. The winglet converts some of the wasted energy in the wingtip vortex to thrust.Another potential benefit of winglets is that they reduce the strength of wingtip vortices

What training is needed for aerospace engineering?
For engineering fields, mathematics. If you do not understand calculus by the end of your first year of college, then it is time to change majors. It would be help to have studied calculus in high school in your senior year. In my first year of AE, my first quarter was the entire year of pre-calculus in high school.
Why is medical oxygen filled to the bottom of the green area on the pressure gauge?
Pressurized oxygen can be very dangerous and pose a hazard of explosion when exposed to heat sources, unlike other common compressed gasses such as nitrogen and carbon dioxide. The less pressurized the oxygen is, the smaller the risk of this happenning. Filling a tank to the gauge minimum instead of the maximum allowable mitigates risk to anyone who may be around it.
What is needed to get a bachlors in aerospace engineering?
If you want to be an aerospace engineer, you should probably actually set your sights on a master's degree, not a bachelor's degree.
Aerospace engineers take full and rigorous coursework in science and mathematics, including everything from physics to mechanical engineering, as well as lab work/applied work.
How much wingspan does a plane need for its own mass?
It is quite simple. There are exact measurements, but as you said each differently sized plane needs a different span due to its mass. Wings are much more complicated than someone may think. They have multiple flaps, each used for specific things. The most commonly known flaps are the "flaps". These are the enormous ones at the very base-rear of each wing that lower during landing to provide an immense decrease in speed. Then there are the Ailerons, located very near the tip of the wing. These control banking, and big planes have two sets. On large planes such as A380s and 747s, there are inboard and outboard Ailerons. Ailerons are combined with the rudder, on the vertical stabilizer or "fin", to create bank turns. Next come the spoilers or air brakes. These are used often, to provide slight speed decreases moslty during landing. There are usually four spoilers on each wing in a row. Finally there are the slats. These are located on the very tips of the wing and are always lowered in only takeoff and landing. They provide extra lift by expanding the length the airflow must travel under the wing and decrease the length over the wing. There are also flaps on the tailplane, which consists of two horizontal stabilizers and one vertical stabilizer. The vertical stabilizer has, as mentioned before, the rudder to control turns. The horizontal stabilizers, or "mini wings on the back of the plane", always have elevators. Not the elevators in a hotel, but flaps that control the planes ascending and descending. They are raised and lowered. In the actual wings themselves there are also heavy fuel tanks and undercarriage (landing gear or "wheels") compartments. So you see that wings can be extremely heavy. There mass must be large, but not wide. When in doubt, make them long. Do not make them too wide because that will create too much airflow over the tops of the wings and your plane won't fly at all. The best thing to do is experiment. If its a paper airplane, than try different things. Make your own flaps and see how they work. Model airplanes are cool too and usually have some flaps similar to real airplanes. I hope I answered your question. I also understand that I probably went overboard quite a lot as well. I am sorry for that, but as for me I love airplanes and the study of aerodynamics.
What are the differences between active low and active high SR flip flop?
Hello
The difference between an active low and an active high SR flip-flop is that with the active low SR flip-flop, the system is activated when the inputs to system are zeros while with the active high SR flip-flop, the system is activated when the inputs to the system are ones.
Why do some aircraft use 28V DC?
Because some systems MUST have at least 24 volts to operate and using 28 is a safeguard against potential voltage drop.
How much does a Breitling Aerospace watch cost?
Breitling Aerospace watches price range from $1,000 US currency to $12,000. The value of all the watches vary from material used in the watch to the capacity of years its insured to work for.
Why are wings are used in missiles?
In order to stabilize them during their flight.
Actually, that's not quite right. Missiles have movable "wings" (a better term for them is "fins"), whose primary purpose is to steer the missile onto target. Most missiles' fins are attached to the main body on a small rotating disk. The missile's guidance package sends commands to each fin, rotating the entire fin up or down slightly, to change the airflow over the fin, and thus change direction of the entire missile.
Standard dumb bombs have fins which are not movable, and serve to stabilize the bomb when dropped, in the same way that feathers on an arrow stabilize it in fight. Modern "smart" bombs work identically to missiles, minus the rocket motor.
Do planes fly uphill from the poles to the equator?
No. Planes fly horizontally, but the concept of horizontal depends on the direction of gravity. Gravity pulls towards the center of the Earth, so "down" at the poles is the same as "down" at the equator, i.e. towards the center of the Earth.
All 'A's. or all with the exception of a B. Make sure your maths and sciences are strong. Also your ECs should preferably involve some science background.
What technology was necessary for the helicopter?
The technology that went into the first helicopters was nothing special. It just took special skills to design the controls for the main rotor blades.
I'm familiar with the invention of the first Bell helicopter that was begun in 1943. Arthur Young designed a model helicopter that he could fly by remote control. Since radio was new, his model had a long electrical cable that was attached to a "trapeze" under the model that transmitted the inputs.
Arthur Young lead a team of engineers to design a full-scale flying prototype. One of the problems they had in the construction was the transmission. The transmission required a gear reduction of 1:47, as I recall. The engineers couldn't do it. So they disassembled Young's model and drew up the pieces to full scale to make the planetary gear transmission that drove the main rotor.
After that, all it took was a lot of testing and adjusting the controls to make make the rotor stable but flyable. They added a stabilizer bar that helped keep the rotor tracking smoothly---which was still in the design of the Bell Model 47.
Is hertfordshire university is good for studying aerospace engineering?
Run a million miles in the other direction! Check the NSS results, you will not expect assignment feedback from that degree factory!
What is meant by an employer has the right toplace restrictions and demands on an employee?
The employer has certain rights, like requiring you to wear a uniform, or prohibiting you from listening to the radio while at work, and you can take a job with that employer or not, your choice. If your employer wants you to travel and you do not want to travel, then do not take that job.
The HS (Harmonized Commodity Description and Coding System) is an international system of names and numbers for classifying traded products created by the World Customs Organization and used in determining tariffs on items shipped internationally.
The HS is based on the fundamental principle that goods are classified by what they are and not according to their stage of fabrication, use, "made in" status or any other such criteria.
The HS nomenclature is logically structured by economic activity or component material. For example, animals and animal products are found in one section; machinery and mechanical appliances, which are grouped by function, are found in another.
The nomenclature is divided into 21 Sections, which, in general, group goods produced in the same sector of the economy.
Each Section is comprised of one or more Chapters with the entire nomenclature being comprised of 97 Chapters.
HS codes have been established along the following hierarchical logic;
• HS-2 refers to the Chapter
• HS-4 refers to the Heading
• HS-6 refers to the Subheading
For example, product code 060110 refers to Chapter 6 (Live trees and other plants: bulbs, roots, etc…), Heading 01 (Bulbs, tubers, tuberous roots…dormant, in growth or in flower, etc….), and Subheading 10 (Bulbs, tubers, tuberous roots…. Dormant).
Further subdivisions (HS-8, HS-10, and HS12) are made by individual countries and trading blocks according to their specific tariff and statistical needs. These "final" product codes are contained in the particular Harmonized Tariff Schedules of the world.
The tariff and tariff-related provisions (e.g.- numerical codes and article descriptions) are presented in tabular format containing several columns. In those columns are contained the headings, subheadings, statistical annotations, article descriptions and rates of duty.

How many credits do you need to get a master's degree in aerospace engineering?
Engineers typically enter the occupation with a bachelor's degree in an engineering specialty, but some basic research positions may require a graduate degree. Engineers offering their services directly to the public must be licensed. Continuing education to keep current with rapidly changing technology is important for engineers. Education and training. A bachelor's degree in engineering is required for almost all entry-level engineering jobs. College graduates with a degree in a natural science or mathematics occasionally may qualify for some engineering jobs, especially in specialties in high demand. Most engineering degrees are granted in electrical, electronics, mechanical, or civil engineering. However, engineers trained in one branch may work in related branches. For example, many aerospace engineers have training in mechanical engineering. This flexibility allows employers to meet staffing needs in new technologies and specialties in which engineers may be in short supply. It also allows engineers to shift to fields with better employment prospects or to those that more closely match their interests. Most engineering programs involve a concentration of study in an engineering specialty, along with courses in both mathematics and the physical and life sciences. Many programs also include courses in general engineering. A design course, sometimes accompanied by a computer or laboratory class or both, is part of the curriculum of most programs. General courses not directly related to engineering, such as those in the social sciences or humanities, are also often required. In addition to the standard engineering degree, many colleges offer 2-year or 4-year degree programs in engineering technology. These programs, which usually include various hands-on laboratory classes that focus on current issues in the application of engineering principles, prepare students for practical design and production work, rather than for jobs that require more theoretical and scientific knowledge. Graduates of 4-year technology programs may get jobs similar to those obtained by graduates with a bachelor's degree in engineering. Engineering technology graduates, however, are not qualified to register as professional engineers under the same terms as graduates with degrees in engineering. Some employers regard technology program graduates as having skills between those of a technician and an engineer. Graduate training is essential for engineering faculty positions and many research and development programs, but is not required for the majority of entry-level engineering jobs. Many experienced engineers obtain graduate degrees in engineering or business administration to learn new technology and broaden their education. Many high-level executives in government and industry began their careers as engineers. About 1,830 programs at colleges and universities offer bachelor's degrees in engineering that are accredited by the Accreditation Board for Engineering and Technology (ABET), Inc., and there are another 710 accredited programs in engineering technology. ABET accreditation is based on a program's faculty, curriculum, and facilities; the achievement of a program's students; program improvements; and institutional commitment to specific principles of quality and ethics. Although most institutions offer programs in the major branches of engineering, only a few offer programs in the smaller specialties. Also, programs of the same title may vary in content. For example, some programs emphasize industrial practices, preparing students for a job in industry, whereas others are more theoretical and are designed to prepare students for graduate work. Therefore, students should investigate curriculums and check accreditations carefully before selecting a college. Admissions requirements for undergraduate engineering schools include a solid background in mathematics (algebra, geometry, trigonometry, and calculus) and science (biology, chemistry, and physics), with courses in English, social studies, and humanities. Bachelor's degree programs in engineering typically are designed to last 4 years, but many students find that it takes between 4 and 5 years to complete their studies. In a typical 4-year college curriculum, the first 2 years are spent studying mathematics, basic sciences, introductory engineering, humanities, and social sciences. In the last 2 years, most courses are in engineering, usually with a concentration in one specialty. Some programs offer a general engineering curriculum; students then specialize on the job or in graduate school. Some engineering schools have agreements with 2-year colleges whereby the college provides the initial engineering education, and the engineering school automatically admits students for their last 2 years. In addition, a few engineering schools have arrangements that allow students who spend 3 years in a liberal arts college studying pre-engineering subjects and 2 years in an engineering school studying core subjects to receive a bachelor's degree from each school. Some colleges and universities offer 5-year master's degree programs. Some 5-year or even 6-year cooperative plans combine classroom study and practical work, permitting students to gain valuable experience and to finance part of their education. Licensure. All 50 States and the District of Columbia require licensure for engineers who offer their services directly to the public. Engineers who are licensed are called professional engineers (PE). This licensure generally requires a degree from an ABET-accredited engineering program, 4 years of relevant work experience, and successful completion of a State examination. Recent graduates can start the licensing process by taking the examination in two stages. The initial Fundamentals of Engineering (FE) examination can be taken upon graduation. Engineers who pass this examination commonly are called engineers in training (EIT) or engineer interns (EI). After acquiring suitable work experience, EITs can take the second examination, the Principles and Practice of Engineering exam. Several States have imposed mandatory continuing education requirements for relicensure. Most States recognize licensure from other States, provided that the manner in which the initial license was obtained meets or exceeds their own licensure requirements. Many civil, electrical, mechanical, and chemical engineers are licensed PEs. Independent of licensure, various certification programs are offered by professional organizations to demonstrate competency in specific fields of engineering. Other qualifications.Engineers should be creative, inquisitive, analytical, and detail oriented. They should be able to work as part of a team and to communicate well, both orally and in writing. Communication abilities are becoming increasingly important as engineers frequently interact with specialists in a wide range of fields outside engineering. Certification and advancement.Beginning engineering graduates usually work under the supervision of experienced engineers and, in large companies, also may receive formal classroom or seminar-type training. As new engineers gain knowledge and experience, they are assigned more difficult projects with greater independence to develop designs, solve problems, and make decisions. Engineers may advance to become technical specialists or to supervise a staff or team of engineers and technicians. Some may eventually become engineering managers or enter other managerial or sales jobs. In sales, an engineering background enables them to discuss a product's technical aspects and assist in product planning, installation, and use. (See the statements under management and business and financial operations occupations, and the statement on sales engineers elsewhere in the Handbook.) Numerous professional certifications for engineers exist and may be beneficial for advancement to senior technical or managerial positions. Many certification programs are offered by the professional societies listed as sources of additional information for engineering specialties at the end of this statement.
