METHOD TO CONTROL REACTIVE THRUST OF TURBOJET ENGINE Russian patent published in 2007 - IPC F02C9/00 

FIELD: aircraft industry; turbojet engines.

SUBSTANCE: proposed method to control reactive thrust of turbojet engine comes to measuring the following parameters on bench: engine thrust R₀, pressure R₀, temperature T₀ and relative humidity B of air, determining partial pressure T₀ of water vapors basing of temperature P_W and relative humidity B of air, and reducing measured thrust R₀ to standard atmospheric pressure by formula R_red=R₀·760/P₀, with additional of correction R_red to thus found thrust ΔR=0,378 Р_W/Р₀·R_red.

EFFECT: provision of stable thrust performance for any engine of this type irrespective of atmospheric condition at bench tests.
