In 1971, the US National Aeronautics and Space Administration (NASA) published a
seminal report—NASA SP-8072—which compiled the results of the early supersonic jet …

During rocket launching, the engine exhaust impinges on the launch structures, such as the
launch platform and the jet deflector, leading to a complex flowfield and generating strong …

Noise generation mechanisms for a perfectly expanded supersonic Mach number, while the
most energetic turbulent kinetic-energy-based POD modes appear to be dominated by lower …

Subscale model tests and a numerical investigation are performed to predict and attenuate
the acoustic level of the Epsilon launch vehicle at liftoff. Requirements for the subscale …

The effects of plate angle on acoustic waves from a supersonic jet impinging on an inclined
flat plate at angles of 30, 45, and 60 deg are numerically investigated. Three-dimensional …

The study of the flowfield and noise characteristics of supersonic impinging jets is important
as these configurations can be found in many engineering applications, such as short …

PAYLOAD vibration due to acoustic waves from the exhaust plume is a significant problem
during the liftoff of a launch vehicle. These acoustic waves are considered to be caused by …

For an adequate understanding of the broadband acoustic phenomena generated by a
rocket exhaust jet impinging on a flame deflector, this study experimentally clarifies the …

The thermal environment of four-engine liquid rocket exhaust plume impinging on the flame
deflector with different impingement and uplift angles is analysed. The supersonic exhaust …

This paper studies the four-engine liquid rocket flow field during the launching phase. Using
three-dimensional compressible Navier-Stokes equations and two-equation realizable k …
