适用范围

"ESDU 87037 presents the more important aspects specific to vectored-jet-thrust@ including the estimation and presentation of short take-off (STO) and ""ski-jump"" (curved ramp) modes. It concentrates on the calculation of airborne distance and on optimising the overall distance from rest to the take-off screen (for STO). The corresponding optimisation processes for ship-based operations are also given. The implications of the configuration for STO performance@ through the effect on airframe aerodynamics and arising from the special requirements on the powerplant@ are discussed. The method of calculation is unique and is based on the possibility with such an aircraft of measuring steady ""point"" performance at airspeeds down to zero. Non-dimensional methods are used in the analysis@ calculation and presentation of take-off performance and depend on the special feature that with this configuration a simple@ direct measure of installed thrust is possible in hover. Methods used to account for jet-induced forces are described."
