The general problem of applying propulsion systems to supersonic aircraft is discussed briefly and it is shown that neither turbojets nor ramjets are entirely satisfactory when used by themselves. A satisfactory solution does result when the powerplants are combined; high supersonic performance then can be achieved without sacrifice of subsonic capability.
In order to avoid the confusion resulting from the comparison of propulsion system performance using the special parameters associated with each type of engine, performance is compared along operating altitude-Mach number paths in terms of thrust and specific fuel consumption only.
The combined propulsion system arrived at offers promise of good performance, light weight, low cost, and simple installation. The realization of these goals depends on an aggressive research and development program.
