Talk:Pratt & Whitney F135

From Wikipedia, the free encyclopedia

How is it that the connected article, F-35 Joint Strike Fighter says the F135 produces 165kN thrust and this article says the F135 delivers 178kN as well as miraculously managing to bleed air to the roll posts each producing 8.7kN and drive a gearbox which also provides 80kN of thrust. Someones sums don't add up - get it right or leave it out!

There are a lot of people who assume things they don't even know about.

Actually this article states that the engine delivers a total thrust of 276kN, far greater than the 165kN stated on the F-35 page. Perhaps someone was just attempting to list the stats like in the F136 page, but failed to do so correctly. I think it's obvious that the Air Force would not want to switch from a 276kN engine to a 178kN one. According to http://www.pratt-whitney.com/prod_mil_f135.asp and http://www.rolls-royce.com/defence_aerospace/products/combat/f136/tech.jsp both the 135 and 136 have the same thrust though they are probably just rounded figures.

I've edited the engine thrust stats to the ones stated here. I used google calculator to convert the pounds of force to kiloNewtons and when summing up the total thrust, I got 177 kN, which if correct, means that the F-35 article is wrong about the 165 kN. AAK 14:27, 9 August 2006 (UTC)
