The phrase "air propulsion" is correct and usable in written English.
It can be used in contexts related to technology, engineering, or physics, particularly when discussing methods of moving objects through the air.
Example: "The development of air propulsion systems has revolutionized the aviation industry, allowing for faster and more efficient travel."
Alternatives: "aerodynamic propulsion" or "atmospheric propulsion".
This paper develops a real-time automotive air propulsion system for light-duty vehicles.
They can be divided into three groups, i.e., rudder equipment, air propulsion systems, and control surfaces affecting the cushion force.
The main design issue for air propulsion is to minimize the propulsor diameter, while obtaining the desired efficiency for minimized power and an acceptably low emitted noise level.
The Balloon Rocket Car, made with paper plates and barbecue skewers, earns children the Rocketeer Patch — "because it uses air propulsion mechanisms, i.e., balloons and straws," Mr. Saxon said.
We also determine that a thrust force of air propulsion results in attenuation of our brand work-energy effect, with high magnitude of a drag force enhancing the effect.
This idea allows the design of new engines, space and air propulsion systems, storage systems (for a beam or solar energy), transmission of energy (over millions of kilometers), creation of new weapons, etc.
One of the companies vying to make the idea a reality, Hyperloop One, which changed its name from Hyperloop Technologies on Wednesday to coincide with the open-air propulsion test in the Nevada desert, has also closed an $80m series B funding round which includes investment from the French national rail company SNCF.
The boots are hooked to a pair of mechanical legs, and they 'kick' a series of balls of bundled money (50 pound notes), shot from an air-propulsion system.
P neumatic transportation uses compressed air for propulsion; air is blown through an airtight tube, propelling a capsule, canister or other vessel.
— As a scientist working for NASA in the 1990s, K. R. Sridhar developed a contraption that could use energy from the sun to transform the elements of the Martian atmosphere into breathable air or propulsion fuel.
If hypersonic air-breathing propulsion systems should become available, the HTO/ HL and APT can evolve to take advantage of them, while the vertical takeoff systems cannot.
