At the very crux of engineering is the desire to problem-solve, optimize, and squeeze out every bit of efficiency possible from the system being built. Aircraft design and aeronautical engineering ...

April 8, 2006 One of the greatest difficulties with vertical take-off and landing (VTOL) aircraft is that they invariably don’t have high speed as one of their attributes. The principles are well ...

The An-70 transport is a high-wing aircraft powered by four 14,000-shp ZMKB Progress D-27 propfan engines with six-blade counter-rotating propellers. Maximum payload is 103,615 lb. Two An-70 ...

High-concept MAV takes off with fixed wings and counter-rotating propellers, allowing it to operate with high aerodynamic efficiency--even in adverse conditions, according to its creator. The military ...

If stardom is measured by camera time and the number of drooling onlookers, then the Green Cri was undoubtedly the star of the recent Paris Green Air Show. The experimental aerobatic electric aircraft ...

In the next few years, the U.S. Navy may finally realize a dream it has had since World War II: the ability to vertically launch and recover a fixed-wing aircraft from a ship deck. A prototype ...

Back in the 1950s, the US Navy was looking for a way to give destroyers and frigates an effective way to take on enemy air attacks—a sort of “first responder” aircraft that could take to the skies to ...
