WebApr 10, 2024 · The X-36 was never a full-size fighter jet -- it was a 28 percent scale copy of what the future fighter jet utilizing the technology might look like. As such, it was only 19 feet long and had a ... WebJul 17, 2024 · When a liquid jet is in a high-speed transverse gaseous flow, an aerodynamic force stimulates a strong disturbing wave on the liquid surface. The breakup process is quite rapid because of the high gaseous speed. In their experiments, high frequency, large amplitude waves controlled by an aerodynamic force were observed.
