In partnership with famend developer, Airplane Heaven, the Microsoft Flight Simulator group at present launched the newest in our Native Legend collection: The Boeing Stratoliner 307. Boeing astonished the world within the late Thirties with the disclosing of the Stratoliner 307, a glimmering and provoking monument to aviation know-how. Born out of the Golden Age of Flight, years within the making, and the main focus of intense efforts by Boeing designers and engineers, the Mannequin 307 stood in a league of its personal as an airliner. The four-engine, long-range plane was the world’s debut high-altitude airliner, the primary to characteristic a pressurized cabin, which allowed it to function as much as 20,000 ft above sea degree. The plane took its maiden flight on December 31, 1938, and was launched into common service on July 4, 1940. Boeing manufactured ten Stratoliners.
Boeing started the event of the 307 within the mid-Thirties in response to airline trade requests for an plane that might function at altitudes above most inclement climate occasions and comfortably fly above the passes of the Rocky Mountains. Engineers primarily based the 307 on the corporate’s B-17C bomber attributable to its aerodynamic efficiency, notably its long-duration flight effectivity. Particularly, Boeing adopted the bomber’s wings, engines, engine configuration, empennage, and touchdown gear for the design. The notable distinction from the B-17 was the fuselage. Boeing designed a round cross-section physique for the 307 with a most diameter of 138 inches. The round design facilitated the pressurized cabin to accommodate excessive altitude flight, and the massive diameter made comfy seating configurations attainable.
Constructed primarily with aluminum alloy, the 307 utilized stressed-skin engineering, the place the metallic exterior works in live performance with the plane’s body for power, flexibility, and to take care of pressurization at altitude. The 307 might carry as much as 33 passengers and 5 crew, together with two pilots and a brand new kind of plane personnel on the time, a flight engineer. The flight engineer was liable for technical elements of the plane’s operation, together with cabin pressurization, energy settings, and electrical elements.
The 307 used engine-driven pumps to take care of cabin pressurization and will function as much as 20,000 ft above imply sea degree whereas holding an inside strain equal to that of 8,000 ft. Its title, a portmanteau of stratosphere and airliner, mirrored its high-altitude working nature. Its spacious cabin accommodated sleeper berths, a galley, a bathroom, and a dressing room along with comfy reclining seats. The Stratoliner represented luxurious journey, a lot within the spirit of ocean liner voyages, an environment that airways sought to imitate.
American industrialist Howard Hughes bought the primary 307 Stratoliner to try setting aviation data. He finally transformed it right into a “flying penthouse.” Pan American Airways (Pan Am) bought three (every designated S-307) and Trans World Airways (TWA) bought 5 (every designated SA-307B). The Pan Am plane used Wright Cyclone engines with single-stage superchargers, and the TWA fashions used Pratt & Whitney powerplants with two-stage sequential superchargers. The 5 that TWA bought had been transformed for army use in World Struggle II. Operated by america Military Air Forces, these airframes used the C-75 designation. By subsequent gross sales to airways and governments, the 307 maintained an operational lineage till 1975, when the final one crashed.
Solely one of many unique ten Stratoliners has survived the years intact, a mannequin initially flown by Pan Am named “Clipper Flying Cloud.” It was meticulously restored to unique situation by 30 Boeing volunteers within the Nineties and flown from Seattle, Washington to Washington, D.C. the place it’s completely housed on the Smithsonian’s Steven F. Udvar-Hazy Middle.
The Boeing 307 Stratoliner measures 38 ft, 7 inches in size, stands 20 ft, 9 inches tall, and has a wingspan of 107 ft, 3 inches. It’s powered by 4 Wright GR-1820-G102A Cyclone radial engines that produce as much as 1,100 horsepower every and switch 3-blade fixed pace propellers. The 307 has a spread of 1,300 miles, a service ceiling of 23,800 ft above sea degree, a cruise pace of 222 miles per hour, and a prime pace of 250 mph.
The Boeing 307 Stratoliner comes with 4 liveries: Boeing Supply, Emerald Harbor, WorldTravel, and AREA (Colombian). Climb aboard, energy up the programs, crank the engines, then set off into the heights on this traditional – out there at present for $14.99. The sky is looking!
