A study of the use of vehicles with lift and throttlable engines to reduce the strain of large accelerations during the boost trajectory of space flight. This Memorandum shows that the equations of motion can be solved by hand methods when control laws, similar to those used by airplane pilots, are applied for various maneuvers. The four basic powered aerodynamic maneuvers considered are: pull up, climb at a constant path angle, leveling off, and cruising at constant altitude. Solutions for trajectory parameters are presented for each flight phase and an example is considered.
