Pratt And Whitneys Impact On The Military And Commercial...

I will do my research on Pratt and Whitney’s significant contribution to the military and commercial aviation throughout the years. I have always been interested in this great company’s ability to learn develop, evolve and advance their engine manufacturing technological capabilities throughout the years thus, making them a force to recon with in the engine field. My focus will be towards the beginning when they started building simple horizontally opposed engines through the radial engines particularly during nineteen fifties. The wasp and the double wasp capable of producing over 400 and 1300 shaft horsepower respectively for that time period which was unheard of will be discussed. I love aviation and have always marveled at the share†¦show more content†¦These airplanes were equipped with four of these engines and transported passengers in comfort. These engines had better performance, reliability and greater fuel efficiency than any other at that time and won the company the prestigious Collier Trophy award. Everything remained unchanged until 1966 when again the company introduced the JT9D turbofan fan commercial use. Which would later be used in the on the iconic and still the best looking airplane in aviation history the Boeing 747 which opened a completely new era in commercial aviation in 1970. The P W Wasp Junior was produced by the thousands. It was a simple, dependable, easy-to-work-on engine. The accessories were attached to the rear and the constant-speed prop hub to the front. Over the years, there have been many different configurations of radial engines, from three-cylinders to nine cylinders, with the seven and nine cylinder versions preferred. When more power is required, a second engine is bolted at an angle to allow cooling air to reach the second set of cylinders. The famous P W â€Å"corn-cob† engine had four banks of seven-cylinder engines attached to one crankshaft. That’s 28 cylinders, and 56 spark plugs to regularly change. The all-time reigning king of radial engines is built by United Aircraft’s Pratt Whitney Division. The man behind the engine was Frederick Rentschler who had designed a revolutionary radial
