The Sea Dragon was a 1962 conceptualized design study for a two-stage sea-launched orbital super heavy-lift launch vehicle.The project was led by Robert Truax while working at Aerojet, one of a number of designs he created that were to be launched by floating the rocket in the ocean.
In 1966 Robert Truax founded Truax Engineering, which studied sea launch concepts similar to the earlier Sea Dragon—the Excalibur, the SEALAR, and the Excalibur S. [10] Truax also designed the Skycycle X-2 , which he unsuccessfully tested on April 15, 1972 and June 24, 1973, and which Evel Knievel unsuccessfully used at the Snake River Canyon ...
A 1962 design proposal, Sea Dragon, called for an enormous 150 m (490 ft) tall, sea-launched rocket capable of lifting 550 t (1,210,000 lb) to low Earth orbit. Although preliminary engineering of the design was done by TRW , the project never moved forward due to the closing of NASA's Future Projects Branch .
A new feature for the engine is the ability to throttle from 100% to 70%. [7] The engine's 150:1 thrust-to-weight ratio is the highest ever achieved for a rocket engine. [8] [9] The first flight of the Merlin 1D engine was also the maiden Falcon 9 v1.1 flight. [10]
SuperDraco is a hypergolic propellant rocket engine designed and built by SpaceX.It is part of the SpaceX Draco family of rocket engines. A redundant array of eight SuperDraco engines provides fault-tolerant propulsion for use as a launch escape system for the SpaceX Dragon 2, a passenger-carrying space capsule.
Some launcher upper stages also use pressure-fed engines. These include the Aerojet AJ10 and TRW TR-201 used in the second stage of Delta II launch vehicle, and the Kestrel engine of the Falcon 1 by SpaceX. [3] The 1960s Sea Dragon concept by Robert Truax for a big dumb booster would have used pressure-fed engines.
A third and new species of seadragon has been discovered. Named the ruby seadragon, it joins its two known counterparts, leafy and weedy, in a group characterized by seahorse-like bodies and ...
Simulating an escape from a rocket failure on the ground, Crew Dragon's SuperDraco engines lifted the capsule from a ground pad at SLC-40 and propelled it to a safe splashdown in the nearby ocean. — Success Demo-1 C204: 2 March 2019 8 March 2019 Uncrewed orbital test flight, successfully docked with the ISS. — Success
