transient thermal response of jet vane thrust control systems has been undertaken. The modeling and simulation procedures utilized are based on the concept that the thermal processes associated with jet vane operation can be put into a transfer function form commonly found in the discipline of automatic controls. Analysis of the transient behavior and equilibration of the combustion chamber pressure, the stability of the combustion chamber pressure, and the effects of erosive burning is presented. Solid rocket performance characteristics, dual thrust solid rockets, rocket motor casings, and transient operation are .

This paper describes the modeling and validation procedure of a single shaft turbojet engine. The model aim is to provide detailed predictions of the flow’s properties at nozzle outlet. Those predictions will be used to design a thrust vectoring system for the engine, and the flight dynamics control .

Calhoun: The NPS Institutional Archive Theses and Dissertations Thesis Collection Modeling transient thermal behavior in a thrust vector control jet vane. An attempt was made to model the transient thermal response of jet vanes used for thrust control. A simple computer model based on lumped capacitance methods using boundary layer convection and stagnation point heating as thermal inputs appeared to adequately predict temperatures for a quarter- scale model.

The report presents heat transfer modeling of Thrust Vector control systems using the PHOENICS computer code. Simple two-dimensional wedged blunt bodies have been examined in supersonic cold flow.
Although some state of the art modeling approaches have been presented for simulating the thermal behavior, these have focused on thermally stable conditions.

Therefore, the chemical investigating of the problem leaded to propose a first kinetic model and its thermal analysis caused modelling the oil thermal behaviour. According to the thrust vector control requirements of fast turn of the missile vertical launching, this design carries out the force analysis of the jet vane which is in the high temperature and high speed jet stream, and calculates the normal force which is generated by the vane, thus calculates the area of the jet : Liu Min Wang, Bo Mo.
From the results of transient thermal 3D CFD simulations of the load case ‘Cooldown’ a model for the respective parameters is derived by means of a Linear Time-Invariant System (LTI) approach. These parameters then serve as transient boundary conditions in an independently running, predictive thermal cabin : David Klemm, Wolfgang Rößner, Nils Widdecke, Jochen Wiedemann.
