A line or axis through an aircraft or a rocket, along which the thrust acts; an axis through the longitudinal center of a jet or rocket engine, along which the thrust of the engine acts. Also known as axis of thrust; center of thrust. McGraw-Hill Dictionary of Scientific & Technical Ter...
View from rear of helicopter. A condition in which one side of a rotor disc produces more thrust than the other. The speed of relative airflow over the advancing blade is higher than that of the retreating blade. The rotor thrust of the advancing blade also is higher than that of the re...
Euler calculations of flow over a complete fighter aircraft Vented vectoring-nozzle has superior thrust coefficient and is lighter in weight because it does not require completely enclosed elbow duct ordinarily used to deflect nozzle flow. Improved nozzle has primary nozzle and three-sided elbow ......

where CL and CD are the lift coefficient and drag coefficient, respectively; CLα is the derivative of the lift coefficient concerning the angle of attack; CLα0 is CLα at the zero lift coefficient; CDmin is the zero-lift drag coefficient; kc is the induced drag coefficient; CLminD is ...
CL . The lift fan and the deflection angle of the 3BSD, 𝛿𝑁,δN, remain constant values for the whole run process, and these two constants need to be determined. Gravity remains the same value. The ground friction coefficient was chosen to be the rolling friction coefficient of a ...
