Statement No.16

The overlap between the ACTION and REACTION halves of the Aircraft's Air Mass Motion System commencing as it does at the Inlet face to the engine's compressor means that as forward speeds above  Mach 0.83  the importance of the Velocity component  of  the  basic  thrust   equation        (Thrust = Mass x Velocity) becomes the more critical and important part of the equation. 

The kinetic energy of an Air Mass in motion goes up by the square  of it's Velocity rapidly outstripping the value of the Air Mass itself.  Consequently, because of the overlap and the  fact that the collision between the ACTION and REACTION halves of the Aircraft's Air Mass Motion Cycle occurs across the face of the Inlet to it's engine the source of it's mechanical power the thrust penalty incurred here dramatically outstrips the value of Air Mass itself in the equation resulting in a quite horrendous drop in the Specific Thrust of the Aircraft i.e., the net thrust per unit of mass flow when operating at supersonic, hypersonic and single stage to orbit speeds.

This one fact alone renders the likelihood of NASA and the United  States envisaged objectives at these speeds being economically achieved a virtual impossibility.  Such an enterprise if pursued could well prove to be commercially disastrous without first eliminating the overlap in Motion Action caused to occur throughout the Aircraft's structure formed by it's jet engine ever since Jet Powered Aircraft were first invented.  The question of course is how, reference, Part No.2
