Aerospace Engineering
Aerospace Engineering is the engineering behind the design, construction and science of aircraft and spacecraft. It is broken into aeronautical engineering and astronautical engineering.

Would the Russians gain an edge if the Su-37 continued to be developed as a multirole fighter?
No, since the technology represented by the SU-37 program, continues to be developed across several other airframes.
Which is better amaesi from aesi or btech in aerospace engineering from ignou?
without any doubt amaesi.it is most challenging exam rather than btech ignou.

mech. engg is reqired 4 aeronotics...........chek the eligibilty criteria in coleges
What is the mission statement for Bell Helicopter?
One Bell. On a Mission.
To change the way the world flies with superior vertical lift that saves lives, preserves freedom and provides customers with exceptional value.
Megatronics is the technical discipline of creating electronic systems that take up as much physical space as possible. An example is creating a computer that takes up an entire room, to do simple arithmetic. Another example is making the servers that run the Internet large enough to fill the core of the Earth. Megatronics is very popular in Texas.
How does adding paperclips to the nose of a paper plane affect its flight?
It shifts the center of gravity forward. If the paper airplane originally had the center of gravity too far back, causing it to nose up and stall a paperclip or two can correct this and produce stable flight. If the paper airplane originally had the center of gravity correctly positioned or was too far forward the paperclip will cause it to nose down and crash.
Is there any helicopter without tail?
No, that is impossible. You see, helicopters must have that tail rotor in order to keep steady. Without one, it would spin out of control in the opposite direction that the main rotor is going. The tail rotor provides a counter form of propulsion that keeps the fuselage (body) of the copter from spinning out of control. The pilot also controls the speed and angle of the tail rotor, so as to turn the helicopter by speeding up or slowing it down. As for Chinooks, those big military helicopters with two main rotors, each rotor spins in the opposite direction to stop from entering a tailspin.
What is the difference between angle of attack and positive angle of attack?
Angle of attack may be negative or positive - it's simply the angle between the wing chord line and the oncoming airflow.
If it's positive then the aircraft will benefit from the lift that is provided, if it's negative then there is no lift (but there's still drag). This is a potentially dangerous situation, unless you wish your aircraft to descend.

What are facts about the first jet flight?
April 18, 1941 was the first flight of the German turbojet powered Messerschmitt Me 262. The British turbojet powered Gloster E.28/39 first flight was a month later on May 15, 1941 making it the second jet to fly.
The first airliner with jet power only was the British Vickers VC.1 Viking G-AJPH, which first flew on April 6, 1948.
What were the first technological advancements that continue to lead to the advancement of flight?
fluid dynamics
What is the purpose of Aerospace companies?
Aerospace companies provide the research, design, development, construction, testing, science and technology of aircraft and spacecraft and are therefore a big part of the industry.
How do missile defense systems help nations?
Missile defense systems are very limited in nature. If one missile gets out of control, it might be shot down as the USS Lake Erie shot down a USA missile in a test on Feb. 14, 2009. If there are several missiles coming at you, they will overwhelm the best defense systems. Missile defense systems do Nothing to stop aircraft bombers. Bombers that fly below radar. Bombers that have stealth anti radar covering. Bombers that carry air-to-air and/or air-to-ground rockets and or missiles. Bombers can get around most missile defense systems.
How is reciprocating motion changed to rotary motion?
Reciprocating motion is the up and down motion.. This motion is converted into ratational motion by the crankshaft.. This because it (crankshaft) is frequently combined with flywheel thus to keep the discontinous reciprocating energy as rotation energy..
Added points.
Crankshaft drive is the entire mechanism that converts the engine's piston up and down motion where as in cylinder a piston is moved as aresult of applied fluid pressure, the actuator provide rotary motion

What does roll on a plane mean?
An airplane can change direction in three ways because it is free in the air. An automobile can change direction to the right or left, and this corresponds to an airplane yawing left or right. The automobile cannot decide to go down or up like an airplane can because it is on solid ground. This down or up change of direction is called pitch. A car also has wheels only on the bottom, and cannot travel on its roof or on one side. An airplane, however, can fly upside down, or on its side just as well as right side up and changing the position of the plane in this way is called roll. A roll is a technique in an airplane where the plane turns upside down then keeps going until it is rightside up again. Roll on an airplane is controlled by the ailerons (the little flaps on the wings).
What is the relationship between aircraft wing and runway length?
Pretty much the more efficient the wing design is, the less runway you will need.
The wing of an aircraft is essential because it is tasked with the generation of lift, the force required to both get an aircraft off the ground and the keep it airborne. During take-off, the former is the primary objective of the wing. The better the wing is at generating lift, the faster the aircraft will get off the ground. Accordingly, the less runway length it will use.
--------------------------------------------------------------------------------------------
There are a lot of factors that come in to play when it comes to designing a wing, and that is where it gets complicated. Such questions as the following are asked: will the wing be swept or un-swept? Long & slender or short & stubby? Winglets or no winglets? What kind of airfoil? etc. These issues are all addressed during the design process.
Ideally, a wing with an elliptical lift distribution is the most aerodynamically efficient when it comes to generating lift. To attain this, the wing is pretty much shaped like an ellipse (a great historical example is the British Spitfire of WWII). However, elliptical wings are very hard to manufacture (which also leads to them being more expensive than your standard rectangular wing). Accordingly, most aircraft incorporate tapered wings which provide a similar effect to elliptical wings (thought not exactly the same) but are much easier and less expensive to manufacture.
What are the OSHA standards for aerospace engineering?
There are no OSHA standards specifically for aerospace engineering. The OSHA General Industry standards would usually apply, although some activities may come under the Construction Industry Standards..
