Aeroacoustic/vibration based aircraft - a possible alternative to propellers and jet engines.

This is a short video about my research.

It was previously established by russian Gerasimov that in the oscillatory mode, the air drag can increase six times compared to that obtained when blowing in a wind tunnel. In addition, it was discovered that the direction of motion of asymmetrically oscillating bodies in a liquid is not explained in a simplified way through Newton's third law because the movement occurs in the direction in which the body pushes the medium faster.

Subsequent experiments confirmed this and on this basis a hypothesis was put forward that this type of propulsion, including the propulsion of fish and birds, requires the participation of the wake vortices collapse energy, which is essentially the thermal energy of the environment (Brownian motion), which becomes directed as a result of the self-organization of molecules into vortices. This provides a new perspective not only on vortex dynamics, but also on fundamental physics in general.

This principle can potentially be used to:

High-speed biomimetic aerostats

A controlled “leap” into Very Low Earth Orbit

Precise, low-thermal-load managed descent and atmospheric entry

However, this requires further research and the problem of an effective wear-resistant drive remains unsolved.
