Q: The aircraft pictured here made its first flight in August of 1931. Can you identify the aircraft, and the engines that powered it?
Q: Name That Aircraft
A: The aircraft is the Sikorsky S-40. It was powered by Pratt & Whitney Hornet engines.
Q: A high-performance turbo-jet engine?
A: The engine was the JT12 (J60). The JT12 would power Rockwell International’s T-28 Buckeye and T-39A Sabreliner, as well as Lockheed’s C140 Jetstar. The JFTD12, a free turbine version of the JT12 used in helicopters, would power Sikorsky’s S-64 Skycrane and CH-54A.
Q: How many acres?
A: Pratt & Whitney initially secured options on 500 acres of land for the East Hartford facility.
Q: Engine unveiled at the Paris Air Show, 1973?
A: Pratt & Whitney unveiled the JT10D engine at the Paris Air Show in 1973. It was a high-bypass, dual spool turbofan in the 25,000 to 30,000-pound thrust class, intended for use in two, three and four-engine configurations on commercial aircraft.
Q: Which airline bought the 10,000th JT8D engine?
A: The milestone engine was shipped to Boeing for installation on a 727 for Alitalia Airlines of Italy.
Q: Which airline reached 100,000,000 miles of flying by June of 1936?
A: The airline: United Air Lines. The aircraft: Boeing 247-D. The engines: Pratt & Whitney Wasp.
Q: How big was the contract?
A: The contract award was worth $1.23 billion.
Q: How many 747s did Pan Am purchase in 1966?
A: There were 25 aircraft in Pan Am’s order. Pan American World Airways announced an order for 25 JT9D-powered 747s in April 1966. The order included 23 747s in passenger configurations and two in cargo configurations. Options to purchase 10 additional aircraft were also part of the agreement. Pan Am was the first carrier to order the 747, just as it was the first to order the 707. The JT9D engine was Pratt & Whitney’s largest engine at the time. Each engine developed 41,000 pounds of thrust, giving the 747 a total thrust of 164,000 pounds – more than twice the thrust of the most powerful commercial engines then in regular service on 707s or DC-8s.
Q: What was unique about Wasp Major No. 5000?
A: Nothing. “The manufacture of the engine was strictly routine.” Pratt & Whitney delivered Wasp Major engine No. 5000 in June of 1950. The group that worked on the assembly of Wasp Major engine No. 1 reassembled for this photo. Pictured from left to right in the front row are Ernie Gagnon, Ralph Richmond, Whitey Kjellquist, Robert Nichols, Steve Micklus, Ed Morrissette and Ed Williams. In the second row are Clifton Simonds, Salvatore Gagliardi, John Bjorklund and Les Benton. Carl Witcher, James Lennon and Herman Frisen are in the back row.
Q: What was the time between overhaul (TBO) when engine JT3D No. 5,000 was delivered?
A: Pratt & Whitney delivered its 5,000th JT3D engine in February 1967. At the time, the engine, which powered various versions of the Douglas DC-8, Boeing 707 and Boeing 720, was the most widely used turbofan engine in the world. When Pratt & Whitney delivered its 5,000th JT3D engine in 1967, the time between overhaul had increased to 10,000 hours, then the highest TBO for any aircraft engine worldwide.
Q: ID the aircrafts and the engines.
A: The aircraft in the foreground is a Ford Tri-Motor. It was powered by Pratt & Whitney Wasp engines. (The comments below correctly note that the original Tri-Motor was powered by Wright engines. The later model was powered by Pratt & Whitney.) The aircraft in the background is a Boeing 727. It was powered by Pratt & Whitney JT8D engines.
Q: Who was the first Pratt & Whitney veteran?
A: Pratt & Whitney’s first veteran was Frederick B. Rentschler. Rentschler, a captain in the U.S. Army, was assigned to inspect the Hisponao-Suiza aircraft engine manufactured by Wight-Martin. Rentschler eventually became the president of the reformed Curtis-Wright Aircraft. Therefore, Pratt & Whitney was founded by a World War I veteran whose aircraft engine passion grew around this Army assignment.
