![]() ![]() Some of the outstanding design features of the H-1 were: a close fitting bell-shaped engine cowling to reduce airframe drag and improve engine cooling gently curving wing fillets between the wing and the fuselage to help stabilize the airflow, reduce drag, and prevent potentially dangerous eddying and tail buffeting and retractable landing gear to reduce drag and increase speed and range (typical of everything or the H-1, the landing gear was so perfectly fitted that the gear fairings and doors are difficult to see without looking closely). The Hughes H-1 was designed for record-setting purposes, but it also had an impact on the design of high-performance aircraft for years to come. His average speed over the 2,490-mile course was 332 mph, and this nonstop flight was truly an outstanding accomplishment. Hughes departed Los Angeles before dawn and arrived at Newark Airport, outside New York City, 7 hours, 28 minutes, and 25 seconds later. have a moderateect -aspratio and were used when Howard Hughes broke the transcontinental speed record in the H-1 on January 19, 1937. The wings now fitted on the aircraft span 31 feet, 9 inches. The H-1 had two sets of wings, The wings Hughes used to break the land plane speed record were of a low aspect ratio and shorter than those with which it is now fitted. Actual performance figures for the aircraft closely matched the predicted design performance. A wind tunnel model of the aircraft was exhaustively tested in the 200-mph wind tunnel at the California Institute of Technology’s Guggenheim Aeronautical Laboratory. The H-1 was powered by a Pratt and Whitney Twin Wasp Junior radial piston engine, which was rated at 700 horsepower at 8,500 feet but which could deliver 1,000 horsepower for high-speed flight. The fuselage was left in its natural polished aluminum finish. Since Hughes did not require a sponsor for the aircraft, the H-1 had no markings except the license number NR258Y (later NX 258Y) in chrome yellow against the dark blue background of the wings, and in black against the doped aluminum rudder. The record was set over a specially instrumented course near Santa Ana, California. On September 13, 1935, Hughes achieved the design goal by flying the H-1 to a new world speed record of 352.322 mph. Long Description The Hughes H-1 racer was developed to be the fastest landplane in the world, Also known as the 1B Racer, it was designed by Howard Hughes and Richard Palmer and built by Glenn Odekirk. His average speed for the 4,000-kilometer (2,490-mile) flight was 535 kilometers (332 miles) per hour. speed record in the H-l on January 19, 1937, flying from Los Angeles to Newark, New Jersey, in 7 hours, 28 minutes, and 25 seconds. The aircraft as it is exhibited here is equipped with the long set. Also known as the Hughes 1B, the H-1 was designed with two sets of wings: a short set with a span of 7.6 meters (25 feet) for speed record flight, and a long set with a span of 9.2 meters (31 feet, 9 inches) for transcontinental flight. On September 13, 1935, Hughes achieved this design goal by flying the H-1 to a new world speed record of 567 kilometers (352 miles) per hour at Santa Ana, California. Summary The Hughes H-1 racer, designed by Howard Hughes and Richard Palmer and built by Glenn Odekirk, was developed to be the fastest landplane in the world.
