Geometric Evaluation of Axisymmetric Thrust-Vectoring Nozzles for Aerodynamic Performance Predictions

“…With these controls established, Eqs. (2)(3)(4)(5)(6)(7)(8)(9)(10)(11) are applied to calculate the algorithmic prediction performance.…”

“…[3][4][5][6]. Assuming that the exit-area deviation from orthogonality with the divergent nozzle centerline is negligible, the effective expansion length is approximated as…”

“…1 Other results showed that silane/hydrogen mixtures were effective pilots for ethylene and kerosene combustion. 4 Ethylene C 2 H 4 is a primary fuel itself and is also produced in large amounts during the combustionof methane CH 4 , ethane C 2 H 6 , and other higher hydrocarbons. 5 Ethylene is often chosen for the hydrocarbon-fueled scramjet engines tests because it is used as a surrogate test fuel for hydrocarbon fuels.…”

Structural Analysis of an Engine Chassis for a Disc-Shaped Airship with Thrust Vector Control

“…They are partly steerable, in order to provide thrust and limited direction control. In addition, they serve to inflate the ballonets and thus, maintain the necessary ballonet overpressure [5,6]. For unconventional airships, major features are distinctively different when compared with the "conventional" type.…”

Experimental and numerical research of a supersonic planar thrust vectoring nozzle via mechanical tabs

“…They are applied in the tactical as well as large caliber rockets and missiles. Over the past decades, researches of the mechanical TVC systems have become of great interest [2]. In their earlier works, authors have developed many semi-empirical models that were applied in twodimensional and three-dimensional geometry flow [3].…”
