Breaking the barrier,he day did not fly that fast. But starting in 1937 mysterious accidents began to occur at high speeds. An experimental early version of what was to become Germany‘s most potent fighter of the war, the Messerschmitt Bf 109, disintegrated as its pilot lost control in a fast dive. Pretty soon other new

Rocket plane spaceflight,owever, as far as American designers of research aircraft were concerned, the evolution of supersonic extreme-altitude rocket aircraft had barely started. After the successful X-1 and X-2 series and the D-558-2 Skyrocket, the next step was a rocket plane that could surpass all of its predecessors in

Man versus robot,can be accurately modeled and simulated. As a result, the areas where direct pilot intervention may be needed due to unexpected behavior of an aircraft/spaceplane are rapidly decreasing. This is especially true for vehicles that have a fixed, predetermined trajectory such as missiles and launch vehi

Conclusions,h the He-176 in 1939, essentially at the same time as the jet age, and arguably ended with the final flight of the X -15 in 1968. Successful rocket aircraft projects of that period were based upon three vital ingredients: a good aircraft design, a good rocket engine, and a great pilot. If any part o

Crash course in rocket plane design,To be able to understand the possibilities, limitations, history and evolution of rocket planes, we must look at how they work. We start with the ‘rocket-’ part, then explore the ‘-plane’ element, and finally investigate the wonderful and dangerous things that happen when you combine them.
