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.

• 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.

Any plane can make a 90 degree turn on the z axis and keep flying.

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

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

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.

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.

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.

yes

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.

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.

of course

Because some systems MUST have at least 24 volts to operate and using 28 is a safeguard against potential voltage drop.

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.

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.

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.

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.

Run a million miles in the other direction! Check the NSS results, you will not expect assignment feedback from that degree factory!

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.

yep!!! definitlely. Wichita is the air capital of the world!!!
