Rotorcraft (2011)
Rotorcraft Overview The rotorcraft industry produces aircraft, powered by either turboshaft or reciprocating engines, capable of performing vertical take-off and landing (VTOL) operations. The rotorcraft sector includes helicopters, gyrocopters, and tiltrotor aircraft. Helicopters, which employ a horizontal rotor for both lift and propulsion, are the mainstay of the industry. Gyrocopters are produced in much smaller quantities, primarily for use in recreational flying. Tiltrotor aircraft, such as the V-22 Osprey1, can take off vertically and then fly horizontally as a fixed-wing aircraft. Rotorcraft are manufactured in most industrialized countries, based on indigenous design or in collaboration with, or under license from, other manufacturers. Manufacturers in the United States of civilian helicopters include American Eurocopter, Bell, Enstrom, Kaman, MD Helicopters, Robinson, Schweizer (now a subsidiary of Sikorsky), and Sikorsky. Bell moved its civilian helicopter production to Canada, with the last U.S. product completed in 1993.2 American Eurocopter—a subsidiary of the European manufacturer and subsidiary of EADS NV—has manufacturing and assembly facilities in Grand Prairie, Texas and Columbus, Missouri. European producers include AgustaWestland, Eurocopter, NHIndustries, and PZL Swidnik. Russian manufacturers including Mil Moscow, Kamov and Kazan helicopters, as well as a number of other rotorcraft related companies, have been consolidated under the Russian government majority-owned OAO OPK Oboronprom.3 (See this report’s Russia -
Northrop Grumman Takes Delivery of VTUAV Prototype from Schweizer Aircraft Company
Northrop Grumman Takes Delivery of VTUAV Prototype From Schweizer Aircraft Company July 3, 2001 SAN DIEGO, July 3, 2001 -- Northrop Grumman Corporation's (NYSE:NOC) Integrated Systems Sector (ISS) took delivery Monday of a second unmanned prototype of the Fire Scout Vertical Takeoff and Landing Unmanned Aerial Vehicle (VTUAV) from Schweizer Aircraft Company, the airframe manufacturer. The company-procured vehicle will be used in Fire Scout VTUAV system risk-reduction testing. Dubbed P-3, the vehicle will include a dual-redundant avionics system similar to the one designed for the production Fire Scout system. Joining a manned VTUAV system in the company-funded, two-vehicle test fleet, P-3 will begin flight tests at the end of the year. The first engineering and manufacturing development (EMD) vehicle, E-1, is expected to be delivered in July, while the EMD flight test program is scheduled to begin in February 2002. Currently in low-rate initial production (LRIP), the Fire Scout system will provide reconnaissance, situational awareness and precision targeting support for the U.S. Navy and forces ashore. The system is designed to autonomously take-off from and land on any aviation-capable ship. It will provide continuous operations with a vehicle endurance of more than six hours and provide coverage 110 nautical miles from its launch site using a baseline payload that includes electro-optical/infrared sensors and a laser designator. The first LRIP system will be deployed by the U.S. Marine Corps and will include three air vehicles, two ground control stations, a data link suite, remote data terminals and modular mission payloads. -

On Sept. 13, 1935, Hughes piloted the H-1 at 352 mph to aviation.” (566 kph) over a measured speed course near Santa Ana, Calif., shattering the existing – Howard Hughes international record of 314 mph (505 kph). It was the H-1 that gave birth to Hughes Aircraft Co., which was established that speed same year. Boeing’s satellite business in El Segundo, Calif., and its helicopter business in Mesa, Ariz., have their roots in the aviation company Hughes founded. But the connection between Boeing and Howard Hughes goes back even further. Hughes was born in Houston in 1905, the son of a wealthy oil industrialist. By 1931, the young Hughes was already a well-known motion picture producer and an emerging pilot with a passion for speed and an eye for accuracy and detail. He admired Charles Lindbergh and had started to make a name for himself as an aviator with a Boeing airplane, the 100A. -
Sailplanes by Schweizer, a History
S € Hit E I Z N A R ll sine Sailplanes by Schweizer A History Paul A. Schweizer and Martin Simons Paul A. Schweizer and his brothers, Ernie and Bill, started to build and fly gliders in 1930 and formed the Schweizer Aircraft Corp. in 1939 to produce sailplanes. Since then the company has produced over 2170 aeroplanes of 22 different types and has become the main source of gliders and sailplanes in the USA. It is now the oldest family-owned aircraft company to have been in continuous operation in the USA. This book tells the story of Schweizer sailplanes and includes a chapter on each of the 22 glider types and variations that were built and flown by the company. It describes how each type was developed, its purpose and gives the details of its construction, special features and how it flew. Outstanding flights made by each type are also included. Specification sheets give precise dimensional details and three-view drawings will assist all interested model builders. Many rare and unique photographs have been borrowed from the company archives to illustrate this book. £39.95 RRP SAILPLANES BY J.\ >J J 5 T L> Ji / SAILPLANES BY >\ >J J 3 T L> Ji / p T\ TJ 1 TV J-J ^/ —J J-J ^ jj yy j J ^ j 51 a T] j1 j j j Airlife England Copyright © 1998 Paul A.
