Nuclear thermal propulsion (NTP) enables unique new robotic planetary science missions that are impossible with chemical or nuclear electric propulsion systems. A compact and ultra lightweight bi-modal nuclear engine, termed MITEE-B (MInature ReacTor EnginE - Bi-Modal) can deliver 1000's of ...
【新的火箭推进方式:美国核热推进Nuclear Thermal Propulsion】热核推进是指利用核裂变能加热工质,再将加热后的高温高压工质定向喷出而获得推力。具有功率高、寿命长、比冲大、不受外界环境影响等特点。 An ov...
Nuclear Thermal Rocket Engines are an alternative to chemical propulsion, and can offer far better specific impulses. Real world example: NERVA. The basic gist of an NTR is that, though they have about the same Thrust Power as a chemical engine, they can use different propellants and get ...
Artist's concept of the DRACO (Demonstration for Rocket to Agile Cislunar Operations) spacecraft, which will demonstrate a nuclear thermal rocket engine. Nuclear thermal propulsion technology could be used for future NASA crewed missions to Mars.(Image credit: DARPA) NASA and the U.S. military ...
NASA and the U.S. Department of Energy have teamed up to fund three design concepts for reactors that could become part of a nuclear thermal propulsion system.
This paper describes the current research and development efforts currently underway within the United States on Nuclear Thermal Propulsion (NTP), with a particular focus on the Demonstration Rocket for Agile Cislunar Operations (DRACO) project, a joint effort of the United States Defense Advanced Pro...
Nuclear Thermal Propulsion technology - Summary of FY 1991 Interagency panel planning An Interagency (NASA/DOE/DOD) technical panel has been working in 1991 to evaluate nuclear thermal propulsion (NTP) concepts on a consistent basis, and to continue technology development project planning for a joint...
-aluminum, and metal ceramic fuels, in contrast to land-based reactors which use uranium dioxide, UO2.These factors provide the naval vessels theoretical infinite range and mission time.For all these considerations, it is recognized that a nuclear reactor is the ideal engine for naval propulsion....
Nuclear thermal propulsion (NTP) involves using the energy from a nuclear reaction to heat fuel that’s fired out of the back of a rocket, like the air from a toy balloon. But with nuclear electric propulsion (NEP), the fission energy is instead used to ionize a gas. “The propellant ...
This concept for a “bimodal” rocket – one which relies on chemical propellants to achieve orbit and a nuclear-thermal engine for propulsion in space – could become the mainstay of NASA and other space agencies in the coming years. According toHoutsand others at Marshall, the dramatic incre...
