Help with homework

Does Anybody know the thrust of the ATV engines in Kn??

I need it for my Homework project.

I hope you mean kN.

I think you are going to have to be more precise. What do you need ATV thrust for? Are you coming up with a problem for a project, or solving one? If you are solving a problem for ATV thrust, you should probably solve the problem.

Edit: But this info is available on Wikipedia, so I'm a little confused about you asking it here.

I need the data for a project involving Orion (which will use ATV thrusters).

I need it to calculate general values for my mission.

(Yes I do mean kN)

If you go to ATV page on Wikipedia, in the panel on the right you can find, "Main engine: 4 × 490N, Aerojet (GenCorp) Model R-4D-11." For a total of 1.96 kN of thrust.

Thank you so much!!

The ATV uses 4x490N engines as main propulsion, and 28x200N engines for RCS manoeuvers.

All of those are hypergolic bipropellant pressure fed engines

Edit : quick note though - Orion's service module will have a different layout of engines than the ATV.

It'll have an array of 8x490N engines (the same as those 4x490N on the ATV) which are planned to be clustered around a refurbished Space shuttle AJ10-190 27kN OMS engine. (The 8x490N engines are there as a backup) and 24x200N RCS engines.

Orion SM shares technology with ATV's SM (solar panels, onboard electronics, etc) and will be built by ESA, but they are not the same.
