The Next Generation Launch Vehicle (NGLV) is a three-stage partially reusable Heavy-lift launch vehicle, currently under development by the Indian Space Research Organisation (ISRO). This vehicle is designed to replace currently operational systems like PSLV, GSLV and LVM3. The project was previously referred to as Unified Launch Vehicle (ULV).
Another propulsion system that may be used is ion propulsion. Project Longshot Nuclear Fission Engine schematic As for future developments, the theoretical possibilities of nuclear based propulsion have been analyzed over 60 years ago, such as nuclear fusion ( Project Daedalus ) and nuclear pulse propulsion ( Project Longshot ), [ 35 ] but have ...
For rocket-like propulsion systems, this is a function of mass fraction and exhaust velocity; mass fraction for rocket-like systems is usually limited by propulsion system weight and tankage weight. [ citation needed ] For a system to achieve this limit, the payload may need to be a negligible percentage of the vehicle, and so the practical ...
The SCE-200 (also referred as Semi-Cryogenic Engine-200) is a 2 MN thrust class liquid rocket engine, being developed to power Indian Space Research Organisation's (ISRO) existing LVM3 and upcoming heavy and super heavy-lift launch vehicles.
In May 1946, the U.S. Air Force launched the Nuclear Energy for Propulsion of Aircraft (NEPA) project to explore the potential of nuclear energy for powering aircraft. [13] [14] This initiative led to a collaborative effort of the Air Force and the U.S. Atomic Energy Commission (AEC) known as the Aircraft Nuclear Propulsion (ANP) program, aimed at developing nuclear propulsion systems for ...
The NEXT thruster has demonstrated, in ground tests, a total impulse of 17 MN·s; which as of 2010 was the highest total impulse ever demonstrated by an ion thruster. [2] A beam extraction area 1.6 times that of NSTAR allows higher thruster input power while maintaining low voltages and ion current densities, thus maintaining thruster longevity.
The Direct Fusion Drive (DFD) is a theoretical spacecraft propulsion system that derives its name from its unique capability to generate thrust directly from nuclear fusion, bypassing the need for an intermediate electricity-generating process.
For the list of predominantly solid-fueled orbital launch systems, see: Comparison of solid-fueled orbital launch systems. Spacecraft propulsion [note 1] is any method used to accelerate spacecraft and artificial satellites. Orbital launch systems are rockets and other systems capable of placing payloads into or beyond Earth orbit.
