Design and Preliminary Analysis of the Variable Axisymmetric Divergent Bypass Dual Throat Nozzle
Journal of Fluids Engineering, 2020Abstract Turbofan engines with afterburners usually have variable nozzle throat area, and the nozzle throat area may increase by 50–100% during afterburning. An axisymmetric divergent bypass dual throat nozzle (ADBDTN) can offer high thrust vectoring efficiency without requiring additional secondary flow in the pitch and yaw directions ...

Abstract Due to its ability to maximize thrust vectoring performance, the bypass dual throat nozzle (BDTN) has an advantage over other fluidic vectoring controls. In this study, numerical simulation is performed to analyze the flow characteristics and performance parameters of an aircraft engine with three different nozzle configurations.

Numerical Investigation of the Thrust Vectoring Performance of a Bypass Dual Throat Nozzle
ASME 2023 Heat Transfer Summer Conference, 2023Abstract Aircraft propulsion systems have become progressively complex due to a recent emphasis on the maneuverability of future fighter aircraft. These systems are capable of providing additional maneuverability to the aircraft. In addition to being able to withstand the high temperatures and pressures generated by modern engines, the ...

Experimental evaluation and numerical simulation of performance of the bypass dual throat nozzle
Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 2020Bypass dual throat nozzle (BDTN) is a modern concept of fluidic thrust vector control. This method able to solve the problem of thrust loss without need the secondary mass flow from other part of engine. Internal nozzle performance and thrust vector angles have been measured in the BDTN experimentally and numerically. A new simple approach is proposed

A fluidic thrust vector control using the bypass flow in a dual throat nozzle
Journal of Mechanical Science and Technology, 2021The present study is to explore an active mass flow control technology for an emerging bypass dual throat nozzle. A new arc-shaped bypass system has been applied to replace the previous V-shaped bypass for the bypass dual throat nozzle, which can decrease the total pressure loss significantly.

Performance study of bypass dual throat nozzle based on numerical simulation
International Journal of Turbo & Jet-EnginesAbstract This study investigates the aerodynamic performance of elliptical cross-section bypass double-throat nozzles (BDTNs) with varying short-to-long axis ratios (b/a = 1.0, 0.8, 0.6, 0.4), using an axisymmetric BDTN as a reference.
