  2. Fuel system icing inhibitor - Wikipedia

    en.wikipedia.org/wiki/Fuel_System_Icing_Inhibitor

    Jet fuel can contain a small amount of dissolved water that does not appear in droplet form. As an aircraft gains altitude, the temperature drops and the fuel's capacity to hold water is diminished.

    An interesting feature of all three German jet engine designs that saw production of any kind before May 1945: the German BMW 003, Junkers Jumo 004 and Heinkel HeS 011 axial-flow turbojet engine designs was the starter system, which consisted of a Riedel 10 hp (7.5 kW) flat twin two-stroke air-cooled engine hidden in the intake, and essentially ...

    Variable speed pumps were replaced with two-speed pumps (each rated at 35,400 US gallons per minute (2.23 m 3 /s) for a discharge pressure head of 865 feet (264 m)), and a flow control valve (adjustable from 22% open to 100% open with a linear flow response) was added to each loop for use in regulating recirculation flow (capable of regulating ...

    The pumps (one for the fuel and one for the oxidizer) in electric-pump feed engines are driven by an electric motor. [19] The Rutherford engine uses dual brushless DC electric motors and a lithium polymer battery. It is claimed that this improves efficiency from the 50% of a typical gas-generator cycle to 95%.

  8. Jet propulsion - Wikipedia

    en.wikipedia.org/wiki/Jet_propulsion

    Jet propulsion is produced by some reaction engines or animals when thrust is generated by a fast moving jet of fluid in accordance with Newton's laws of motion.It is most effective when the Reynolds number is high—that is, the object being propelled is relatively large and passing through a low-viscosity medium.

  9. Secondary air injection - Wikipedia

    en.wikipedia.org/wiki/Secondary_air_injection

    Pumped air injection systems use a vane pump called the air pump, AIR pump, or colloquially "smog pump" turned by the engine via a belt or electric motor.The pump's air intake is filtered by a rotating screen or the vehicle air filter to exclude dirt particles large enough to damage the system.
