The Gorlov helical turbine (GHT) is a water turbine evolved from the Darrieus turbine design by altering it to have helical blades/foils. Water turbines take kinetic energy and translate it into electricity. It was patented in a series of patents from September 19, 1995 [1] to July 3, 2001 [2] and won 2001 ASME Thomas A. Edison.
Simplified full-flow staged combustion rocket diagram. Raptor is powered by subcooled liquid methane and subcooled liquid oxygen in a full-flow staged combustion (FFSC) cycle. . FFSC is a twin-shaft staged combustion cycle that uses both oxidizer-rich and fuel-rich preburne
With a conventional chemical propulsion system, 2% of a rocket's total mass might make it to the destination, with the other 98% having been consumed as fuel. With an electric propulsion system, 70% of what's aboard in low Earth orbit can make it to a deep-space destination. [24] However, there is a trade-off.
6 kW Hall thruster in operation at the NASA Jet Propulsion Laboratory 3D sketch of an electromagnetic propulsion fusion plasma thruster. Spacecraft electric propulsion (or just electric propulsion) is a type of spacecraft propulsion technique that uses electrostatic or electromagnetic fields to accelerate mass to high speed and thus generating thrust to modify the velocity of a spacecraft in ...
In the Known Space universe, constructed by Larry Niven, Earth uses constant acceleration drives in the form of Bussard ramjets to help colonize the nearest planetary systems. In the non-known space novel A World Out of Time , Jerome Branch Corbell (for himself), "takes" a ramjet to the Galactic Center and back in 150 years ships time (most of ...
Spaceflight (or space flight) is an application of astronautics to fly objects, usually spacecraft, into or through outer space, either with or without humans on board.Most spaceflight is uncrewed and conducted mainly with spacecraft such as satellites in orbit around Earth, but also includes space probes for flights beyond Earth orbit.
Astrophysical fluid dynamics is a branch of modern astronomy which deals with the motion of fluids in outer space using fluid mechanics, such as those that make up the Sun and other stars. [1] The subject covers the fundamentals of fluid mechanics using various equations , such as continuity equations , the Navier–Stokes equations , and Euler ...
The total delta-V capability of the spacecraft is about 2,700 m/s (6,000 mph). [17] Juice has a fixed 2.5 meter diameter high-gain antenna and a steerable medium-gain antenna, both X-and K-band will be used. Downlink rates of 2 Gb/day are possible with ground-based Deep Space Antennas. On-board data storage capability is 1.25 Tb. [1]
