For a horizontal tail or canard, the pitching moments which must be countered are most directly related to the wing mean chord (Cw). This leads to the “horizontal tail volume coefficient,
The gross thrust coefficient (Cfg) is a measure of the nozzle efficiency and accounts for nozzle losses due to friction, angularity, expansion, leakage and cooling air throttling
The Mach number of a normal shock wave is always greater than unity in the upstream and less than unity in the downstream, the static pressure always increases across the shock wave
Mx= Up Stream Mach Number
It is mechanical stress created by any change in the temperature of a material. In general, the greater the temperature change, the higher the level of stress that can occur.
considerable magnitude is induced in the supercharger impeller by reason of the high rotational speeds necessary to obtain the desired pumping effect.
