Numerical Investigation on Transient Effect of Jet Interference Characteristics of Lateral-Jet-Controlled Spinning Missile

نویسندگان

چکیده

At present, there is no publicly published research on the unsteady interference effect in start-up process of lateral jet control spinning missile. The variation aerodynamic characteristics during missile still unclear. Therefore, numerical method based three-dimensional compressible Navier–Stokes equations and sliding mesh used to study starting jet. Based verification simulation this paper, flow field under conditions non-rotation rotation simulated, two given. influence lateral-jet-controlled analyzed. mechanism resulting change analyzed through structure at different moments after starts. results indicate that pulse control, fins have a delay compared with projectile body. duration caused by high-pressure region upstream nozzle shorter than low-pressure downstream nozzle. separation reattachment near strong characteristics. wake has most obvious Fin1. pressure side direction Fin1 increases, while opposite contrast.

A Further Wind Tunnel Investigation of Underwing Jet Interference bY

SUMMARY Further experiments, to investigate the interference of the Jet stream issuing from a high bypass ratio engine mounted below a wing, are described. Tests have been made with a two-dimensional wing, and two nozzle shapes representing engues with different fan cowl lengths. A Jet blonng from these nozzles produced negligible interference on the wing upper surface. However, a change in th8...

Transient Characteristics of a Fluidic Device for Circulatory Jet Flow

In this paper, we report on the design, simulation, and experimental analysis of a miniaturized device that can generate multiple circulated jet flows. The device is actuated by a lead zirconate titanate (PZT) diaphragm. The flows in the device were studied using three-dimensional transient numerical simulation with the programmable open source OpenFOAM and was comparable to the experimental re...
