How does nuclear missile propulsion work?

lionel4power:
How does nuclear missile propulsion work?

Basically image a miniature reactor which has a suitable nuclear fuel packed into a sub critical mass along with the requisite control rods , u remove the rods to start the reactor.

The thermal energy now being generated can be used to heat up the air much like in a jet engine to create thrust.

Unlike a jet engine here u need to use a heat exchanger which will draw heat from the reactor and heat up the incoming mass of air inside a chamber to very high temperatures which will expand and propel the missile forward.

This is the basic idea.

It is kind of complicated when u go into details whether it is a close looped system or a open looped system or the type of reactor being used , different reactors different way to get the propulsion work etc

It is basically a doomsday device

Also I wonder how they took care of radiation leakage, if it is a open loop system there will be radiation spillage when the reactor comes online due to necessasity of direct contact of the working medium (air) with the nuclear element. Basically it will be leaking radiation of varying degrees along it flight path.

If it is a closed loop system then it mandates the development of high efficiency supercritical CO2 brayton thermal conversion type systems. it will not leak radiation. But such systems r still to be developed , not sure though.

Anyways I don't have a freaking idea about all these just assuming

Okay. I understand now.

But won't it require a compressor to Kickstart the process? Similar to an S-RAM combustion engine.

Nemesis8u,whatever happened to the Sitara? Meant to be a 2 engine LIFT and ground attacker with a very good 9.5 T external payload capacity,it flew some 5 yrs back,IIRC. If this project was killed after successful prototypes were built those involved deserve the rope-I'm not joking!

Most probably shelved

IAF is not interested in duplicating trainers since the hawks were bought

Also the morons were struggling with induced spin recovery. Spin recovery is a important criteria in trainer aircrafts.

I would have written some more points but what's the point when the country is full of morons

Compressor requirement will be dictated by the operational speed of the missile and other things

Speed of the missile is subsonic u will need a compressor

Speed is supersonic or higher u don't require a compressor.

U don't need a compressor to kick start the nuclear propulsion

What u need is the desired air flow rate inside the combustion chamber housing the heat exchanger which is dependent on the speed and design on the missile.

This can be done with compressor if u don't have the desired speed and the compressor is not required if u have the desired speed. Therefore booster rockets is used to propel the article to the required high speed where the nuclear reactor is switched on and the propulsion becomes self sustaining due to availablity of the desired air mass flow.

How feasible do you think it is as compared to electric propulsion?

I'm of the opinion that electric propulsion if well researched could be the future of travel. Both in outer space and aeronautics.

Electric propulsion ?

So tell me what sources of energy is going to provide electric propulsion ?

In outer space, solar energy....


In within earth, miniaturized nuclear batteries.


This type of battery was developed by Baek Kim and Jae Kwon at the University of Missouri, uses the betavoltaic process to generate electricity. A betavoltaic device, as the name implies, is fairly similar a photovoltaic device — but instead of generating electricity from photons, it generates electricity from beta radiation — i.e. high-energy electrons that are emitted by radioactive elements. A betavoltaic device is constructed in almost exactly the same way as a photovoltaic cell: a piece of silicon (or other semiconductor) is wedged between two electrodes, and when radiation hits the semiconductor it produces a flow of electrons (voltage, electricity).

Like i said before. .. Further research into this area could yield results.


Another possibility is laser beamed-energy propulsion system which should provide a means for inter-galactic space voyage.

This are highly advanced technologies which would take decades to design and perfect. But i see great potential in them

See u urself gave the answer
Better than I could have done

I have very little knowledge in these fields

Tell us how the spin recovery ended up and at least a broad picture of the bolded above. Is this is a finished product for which one can buy the production rights?

Not well IMO becz no info on the tests which was scheduled to happen long time ago.

No, it is not even a pre-production model.

So is the mid air refueling probe for training or CAS aircrafts need those as well ?

Primarily for range increase with adequate combat payload.

Hawk 200+ (Combat Hawk)apparently has radar and lots of modern attack features. So quite better than Alpha Jet. UK or India won't mind selling as a replacement for Alpha Jets . The Super Tucano does not quite replace Alpha Jets. Which is something fast that can be used in-country for sir to air and air to ground operations.

This is a topic that doesn’t get much attention on the thread, we need to replace the Alpha jets !

right now, the Alphas are seen as COIN workhorse. Imo the eyes if the brass are concerned with replacement of the COIN aspect of the Alphas & not the other capabilities
