The phrase "air expansion" is correct and usable in written English.
It can be used in contexts related to physics, engineering, or any discussion involving the increase in volume of air due to temperature changes or pressure variations.
Example: "The air expansion in the balloon caused it to rise higher into the sky."
Alternatives: "expansion of air" or "air volume increase".
So there are no worries regarding air expansion on take off.
The coalition statement said: "The implications of today's ruling are profound, not just for Heathrow but for air expansion plans across the UK.
The key idea of the method was to use air expansion energy to do work.
However, the traditional pneumatic-hydraulic transmission is energy dissipation because the air expansion energy existing in the compressed air is wasted.
During the expansion process, the heat regeneration subsystem heats the high-pressure air to improve the entrance enthalpy of starting point of air expansion.
From then on, very little study on any type of sustainable vehicle driven by pneumatic-hydraulic transmission has been reported [14, 15], especially that using air expansion energy.
But due to the proximity of the explosion, it was complicated to shoot: we strongly felt the air-expansion caused by the blast, the extremely loud sound and obviously your heart accelerates a little.
The Regenerative Storage Heater (RS H is employed in Hypersonic Wind Tunnel (HWT) to prevent liquefaction of air during expansion in the high Mach number nozzles.
It is also revealed by an exergoeconomic analysis that, for the best trade-off solution, the investment costs of the compressor and the two heat exchangers recovering compression heat and heating up compressed air for expansion should be reduced (particularly the latter), while the thermodynamic performance of the gas engine need to be improved significantly.
In an era of significant air traffic expansion characterized by a rising congestion of the radiofrequency spectrum and a widespread introduction of Unmanned Aircraft Systems UAS, Global Navigation Satellite Systemsms (GNSS) are being exposed to a variety of threats including signal interferences, adverse propagation effects and challenging platform-satellite relative dynamics.
Democratic Rep. Henry Waxman, a congressional force on clean air and expansion of Medicaid during his 20 terms, has decided to retire.
