One trouble with air is that it’s mostly nitrogen -which is not much use in combustion engines.
Today’s invention is a mobile cart or trolley which helps eg carrier-based aircraft take off by supplying extra oxygen.
It achieves this by containing a cylinder of compressed oxygen which it sprays into the jet engine intakes as both plane and trolley move in unison along the deck.
This provides a controllable additional burst of engine power -enabling shorter and/or more heavily-loaded takeoffs to occur (without breaking the existing steam catapult mechanisms).
