# This Is What 13,150 Kilograms Of Jet Engine Force Looks Like In Testing

Image Cache: To fly a fast jet you need a lot of thrust. The General Electric F110-GE-129 certainly provides that: At its peak output, it generates over 13,154kg of force. Browse through the cool photos, animations and diagrams in Gizmodo's Image Cache here.

In this image, you can see Senior Airman Daniel San Miguel overseeing a series of tests on a F110-GE-129 engine at Misawa Air Base, Japan. This image shows the afterburner phase of its operation, with the intense heat and force of the engine glowing bright against the deep black of the test chamber. The engines are tested many times at peak output before they make it into jets such as the F-16.

You can't just convert pounds to kilograms to get force. Kilograms is a unit of mass, not force. The engine produces between 131kN to 142kN of force (thrust).

I think they have a script or something that changes pounds/feet/miles into equivalent metric values. But luckily it says "x weight of force" so the conversion to kgf seems valid.

29k lbf is 129 kN lel.

Although 901 slugs sounds a bit cooler.

You can, but you shouldn't. There is a non-SI unit - the Kilogram-force (kgf), formerly known as the Kilopond, equal to 9.80665N. I know it used to be used in rocketry by some metric countries, because it simplifies some calculations around specific impulse, lift-off thrust etc. I'm pretty sure it has some other niche uses where gravity is a given.

Yeah I come up with 131 kn to
13358kgf

Take that three headed monster!!!
