Air intake
An air intake (or simply an “intake”) is a part which supplies intake air, a resource required by jet engines. To do so they must be in their “Open” state and inside an oxygenated atmosphere, such as that of Kerbin or Laythe.
Usage
Intake air collected varies proportionally with speed and inversely with altitude. Intakes cause the same amount of drag whether open or closed.[1]
Seaplanes and boats have also been made with unorthodox use specifically of the XM-G50 Radial Air Intake. With 1.0.5, improved hydrodynamics make this unnecessary for building boats or seaplanes. Intakes can also be used as a sort of nose cone to reduce drag on rockets.[1]
