Powerplant: 8× Pratt & Whitney TF33-P-3/103 turbofans, 17,000 lbf (76 kN) each
I want to learn to fly a WWII vintage Spitfire. How can I do this?
sc0tt.rm below: Apparently they are TF33-P-3s. I couldn't believe they had never been re-engined or upgraded. Boeing proposed replacing the pairs of TF33s with single RB211-535-E4s (at 43,100 lb.s.t) on a per flying hour lease scheme at a projected saving of over $5 billion. The USAF audited the figures and decided they would be better off maintaining the stock engines because they could only save $400M over 40 years. The 'Science Board' claims the USAF got their sums wrong and the savings would be $9 billion and more with current operations in Afghanistan because the USAF priced all the fuel as if delivered to home base instead of having to be in flight refueled at 10x the cost (see second link below).
How much capital investment is needed to start an airline business?
I find the previous answer of 17,000 pounds interesting. I am a flight engineer on the E-3, which also uses the P&W TF33-100A (notice the package difference). Ours produce 20,000lbs of thrust and that is with two generators strapped to each engine. I'm not saying he is wrong, maybe the BUFFs are downrated since it has EIGHT.I Will agree with Chris on that answer
hey poeple can you answer this qeastion about mial 1st class air mial?plese?
Eight Pratt & Whitney engines TF33-P-3/103 turbofan
Each engine up to 17,000 pounds (7,650 kilograms)
The B-52 came in two different engines B-52A-G had the Pratt and Whitney J57-P-19W or 29W this engine makes 13,750 lbs of thrust. The B-52H has the TF33-P-3/103 this engine makes 17,000 lbs of thrust. I hope this was helpful.
