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.
Another popular theory held that the maxims were first spoken by the Delphic oracle, and therefore represented the wisdom of the god Apollo. [10] Clearchus of Soli , among others, attempted to reconcile the two accounts by claiming that Chilon, enquiring of the oracle what was best to be learnt, received the answer "Know thyself", and ...
The backbone of any electric gate, whether automatic or not, is the electric gate motor, two distinct motor types exist hydraulic, or electromechanical. This is the electric device which actually enables the electric gate to open and close without having to manually push the gate.
An electric multi-turn actuator on a gate valve. A gate valve, also known as a sluice valve, is a valve that opens by lifting a barrier (gate) out of the path of the fluid. Gate valves require very little space along the pipe axis and hardly restrict the flow of fluid when the gate is fully opened.
With Apollo 12 improved magnetometers were placed on the Moon as part of the Lunar Module/Apollo Lunar Surface Experiments Package (ALSEP). [23] [24] The magnetometer continued to work several months after that return module departed. As part of the Apollo 14 ALSEP, there was a portable magnetometer.
Apollo 11 space-flown silver Robbins Medallion from the first spaceflight to land on the Moon.Presented to Wally Schirra by Neil Armstrong.. NASA space-flown Gemini and Apollo medallions were mission-specific commemorative medallions, often astronaut-designed, which were approved by NASA and carried aboard the mission spacecraft into orbit.
Apollo 16 Active Seismic Experiment. The new mortar base used to improve the experiment after problems were encountered with Apollo 14's. The mortar, geophones, and thumper were stored on the first subpackage. The base of the mortar box was stored on the second subpackage. Three grenades were fired, up to a distance of 900 m. [6]
[8] [9] [10] For example, if an IMU installed in an aeroplane moving along a certain direction vector were to measure a plane's acceleration as 5 m/s 2 for 1 second, then after that 1 second the guidance computer would deduce that the plane must be traveling at 5 m/s and must be 2.5 m from its initial position (assuming v 0 =0 and known ...
