Apollo alkaline fuel cell Alkaline fuel cells played a key part in the success of the 1960s U.S. Space Program that put a man on the moon for the first time. The AES R&D Group, led by Karl Kordesch of the Graz University of Technology in Austria, improved this fuel cell and adapted it for terrestrial, undersea, and extra-terrestrial usage. [24]
Apollo Ultralight Aircraft is a Hungarian aircraft manufacturer based in Eger.The company specializes in the design and manufacture of ultralight aircraft, gyroplanes and ultralight trikes, in the form of kits for amateur construction and ready-to-fly aircraft for the European Fédération Aéronautique Internationale microlight and the American light-sport aircraft categories.
The oil collects in sump (1), is withdrawn continuously by scavenge pump (2) and travels to the oil tank (3), where gases entrained in the oil separate and the oil cools. Gases (6) are returned to the engine sump. Pressure pump (4) forces the de-gassed and cooled oil (5) back to the engine's lubrication points (7).
Pogo oscillation is a self-excited vibration in liquid-propellant rocket engines caused by combustion instability. [1] The unstable combustion results in variations of engine thrust, causing variations of acceleration on the vehicle's flexible structure, which in turn cause variations in propellant pressure and flow rate, closing the self-excitation cycle.
Placing the oil pump low-down uses a near-vertical drive shaft, driven by helical skew gears from the camshaft. Some engines, such as the Fiat Twin Cam engine of 1964, began as OHV engines with an oil pump driven from a conventional camshaft in the cylinder block. When the twin overhead cam engine was developed, the previous oil pump ...
The fuel pump delivered 15,471 US gallons (58,560 litres) of RP-1 per minute while the oxidizer pump delivered 24,811 US gal (93,920 L) of liquid oxygen per minute. Environmentally, the turbopump was required to withstand temperatures ranging from input gas at 1,500 °F (820 °C) to liquid oxygen at −300 °F (−184 °C).
A diagram of a pumpjack. A pumpjack is the overground drive for a reciprocating piston pump in an oil well. [1]It is used to mechanically lift liquid out of the well if there is not enough bottom hole pressure for the liquid to flow all the way to the surface.
