PongSats are high-altitude "near-space" missions that hold a probe or other project that can fit inside a ping-pong (table tennis) ball.The launch program is run by a volunteer organization, JP Aerospace (which also provided balloon launch services for the Space Chair.)
Catapult was founded by engineers Shaun Holthouse and Igor van de Griendt, [3] and is today led by CEO Will Lopes. In 1999 the pair were working with the Cooperative Research Centres during a project with the Australian Institute of Sport seeking to replace laboratory-based performance testing with microtechnology, as athletes were not exerting themselves in lab conditions in the same way as ...
The West Spring Gun was a bomb-throwing catapult used by British, Canadian and Australian forces during World War I. It was designed to throw a hand grenade in a high trajectory into enemy trenches .
A mass driver or electromagnetic catapult is a proposed method of non-rocket spacelaunch which would use a linear motor to accelerate and catapult payloads up to high speeds. Existing and proposed mass drivers use coils of wire energized by electricity to make electromagnets , though a rotary mass driver has also been proposed. [ 1 ]
Dead ball When the ball either bounces twice on the table or hits the floor. Deep A shot hit long, toward the back of the table. Some also use the term to describe a player who is playing deep, far away from the table. Deuce At 10-10 a player must win the set by two points such as 12-10, 13-11, 14-12 etc. Double bounce
The launched roller coaster is a type of roller coaster that initiates a ride with high amounts of acceleration via one or a series of linear induction motors (LIM), linear synchronous motors (LSM), catapults, tires, chains, or other mechanisms employing hydraulic or pneumatic power, along a launch track.
The type of wood or synthetic layers used to make up the blade will determine the blade's speed. The different types of rubber sheets affect the level of spin, speed, and other specific playing characteristics. Racket construction and new rubber technology contribute significantly to the amount of deviation from the expected ball flight path. [3]
A rocket sled launch, also known as ground-based launch assist, catapult launch assist, and sky-ramp launch, is a proposed method for launching space vehicles. With this concept the launch vehicle is supported by an eastward pointing rail or maglev track that goes up the side of a mountain while an externally applied force is used to accelerate ...
