A nuclear lightbulb is a hypothetical type of spacecraft engine using a gaseous fission reactor to achieve nuclear propulsion. Specifically it would be a type of gas core reactor rocket that uses a quartz wall to separate nuclear fuel from coolant / propellant .

Basically a Nuclear Thermal Rockets (NTR) is a nuclear reactor where the propellant is the coolant. And instead of the coolant being directed into a cooling tower, it instead exits out the exhaust nozzle, creating thrust. They use the heat generated from a …

2018年5月20日 · The nuclear lightbulb is a closed-cycle gas-core nuclear propulsion system. It uses quartz to separate the nuclear fuel from the propellent, thus eliminating the radiation problems with open-core designs. Unfortunately, quartz melts at <2000 degrees Celsius, limiting the temperature of the engine.

1991年1月1日 · The nuclear light bulb concept provides containment by keeping the nuclear fuel fluid mechanically suspended in a cylindrical geometry. Thermal heat passes through an internally cooled, fused-silica, transparent wall and heats hydrogen propellant.

The nuclear light bulb is a multiple-cavity gaseous nuclear rocket engine in which energy is transferred by thermal.radiation from gaseous nuclear fuel through internally cooled transparent walls to seeded hydrogen

2020年1月1日 · Unlike the open gaseous core model, the nuclear lightbulb model uses complex heat exchangers to allow for heat transfer between the nuclear core and the rocket nozzle before discharging the propellant.

The Nuclear Light Bulb (NLB) concept is an advanced closed cycle space propulsion rocket engine design that offers unprecidented performance characteristics in terms of specific impulse (greater than 1800 s) and thrust (greater than 445 kN).

A nuclear lightbulb is a hypothetical type of spacecraft engine using a gaseous fission reactor to achieve nuclear propulsion. Specifically it would be a type of gas core reactor rocket that uses a quartz wall to separate nuclear fuel from coolant/propellant.
