Kaman Aircraft - Kaman Industrial Technologies

Kaman Aerospace /kÉ™ËˆmÉ'Ën/ is an American aerospace company, with headquarters in Bloomfield, Connecticut. It was founded in 1945 by Charles Kaman. During the first ten years the company operated exclusively as a designer and manufacturer of several helicopters that set world records and achieved many aviation firsts.

In 1956, Kaman began to diversify as an aerospace subcontractor of McDonnell Douglas, Grumman and others. In the mid-1960s Kaman diversified outside of the aerospace industry, using the expertise Kaman had gained in composite materials and the end of the need for skilled woodworkers to craft wooden rotor blades. Charles Kaman, a guitarist as well as an aerospace pioneer, worked with his engineers and other musicians to create the round-backed, composite-body Ovation guitar, which led to the eventual creation of Kaman Music (now KMCMusicorp). Kaman Music was an independent distributor of musical instruments and accessories, and a major producer of guitars and guitar parts and accessories.

History

Charles Kaman founded the company in December 1945 with $2,000 of capital and his invention of the servo-flap controlled rotor.

January 15, 1947Â: K-125 - Kaman's first helicopter; Kaman selected an intermeshed contrarotating twin rotor design.
July, 1949Â: K-225 - An improved version of the K-125; the U.S. Navy bought two and the U.S. Coast Guard one for $25,000 each. Later, they received the H-22 designation.
December 1951Â: A modified K-225 equipped with a Boeing 502 (YT50) turboshaft engine becomes the world's first gas turbine powered helicopter. This aircraft is now at the Smithsonian Institution's National Air and Space Museum.
1953Â: Kaman produced the first electrically powered drone
April 1953Â: Ordered for the U.S. Marine Corps, the HOK-1 first flies; Air Force version was the H-43A Huskie
1954Â: K-16 A V/STOL designed around a rotoprop
March 1954Â: A modified Kaman HTK-1 becomes the world's first twin-turbine powered helicopter
September, 1956Â: HH-43 HuskieÂ â€" A variant of the OH-43, equipped with a Lycoming T-53 gas turbine engine

July 1957Â: QH-43 - A HTK-1 modified as a UAV

In the late 1950s, Kaman built the Kaman K-17, an experimental tip jet powered helicopter using a Blackburn Aircraft-built Turbomeca Turmo turbine powering a compressor delivering cold air to the rotor tips.

The HU2K-1, selected by the U.S. Navy as a general purpose naval helicopter, makes its first flight on July 2, 1959. It enters service as the UH-2A Seasprite in 1962.

March 1960Â: Kaman develops and flies the first all-composite main rotor blade.

In October 1961 the H-43 Huskie set an altitude record of 10,000Â m (33,000Â ft) and rate of climb records. Anton Flettner who emigrated to the United States and became the chief designer for Kaman Aircraft, creating the Kaman HH-43 Huskie

During the Korean and Vietnam Wars, the Huskie flew more rescue missions than all other aircraft combined, with the best safety record of any U.S. military aircraft.
1962Â: UH-2A / B production begins
January 1964: First flight of Kaman's experimental Convertiplane equipped with a GE J-85 turbojet engine and wings from a Beechcraft Queen Air. The aircraft achieves speeds of over 320 km/h
1965: TomahawkÂ â€" A Seasprite modified with stub wings and a pair of twin guns side-by-side under the nose. Kaman's proposal for the U.S. Army 's interim gunship helicopter between the AAFSS (AH-56) and AAH (AH-64) competitions. Lost to the Bell 209 (AH-1 HueyCobra)

Due to the limited power of its single engine, the Seasprites are modified for the U.S. Navy into twin turbine helicopters.

1969Â: U.S. Navy begins Light Airborne Multi-Purpose System (LAMPS) development to obtain an onboard helicopter for escort ships
1971Â: SAVERÂ â€" The Stowable Aircrew Vehicle Escape Rotoseat is the first jet-powered autogyro with telescoping rotor blades
May 1973Â: SH-2F SeaspriteÂ â€" The LAMPS Mk I enters U.S. Navy service

July 1976Â: Kaman designs and begins manufacturing the K-747 blade, the world's first production all-composite rotor blade for the Bell AH-1 Cobra helicopter. Total production exceeds 4,000 blades.
January 1991Â: Magic Lantern, a new laser-based mine countermeasures system, is deployed in the Persian Gulf during Operation Desert Storm. It is highly successful in locating mines.
February 1993Â: SH-2G Super SeaspriteÂ â€" The new version of the Seasprite, with new avionics, mission electronics and GE T-700 engines, enters U.S. Navy service
August 1994Â: K-1200 K-MAXÂ â€" a purpose-built helicopter with intermeshing rotors specializing in external load operations.
November 1998Â: The Egyptian Air Force accepts delivery of its 10th SH-2G Super Seasprite for use in anti-submarine warfare missions, completing the order and becoming the first international customer to operate the aircraft.
August 1999Â: New Zealand approves purchase of SH-2G(NZ).
January 2000Â: Australian SH-2G(A) begins initial flight testing.
January 2001Â: U.S. federal government purchases 5 K-MAX for Peru.
October 2002Â: The 5 Peruvian K-MAX are transferred to the Colombian Army where they are still in service as of 2008.
June 2008Â: All Royal Australian Navy SH-2G Seasprite helicopters are withdrawn from service and returned to supplier as budget blew-out and contract specifications unable to be met.
January 31, 2011Â: Charles Kaman, founder of Kaman Aircraft died in Bloomfield, Connecticut.

In June 2008 Kaman acquired Brookhouse Holdings Limited, a world leading composite development company based in the United Kingdom, and renames it Kaman Composites UK Ltd. In November 2015, Kaman announced that it was acquiring GRW Bearing GmbH for $142.9 million. GRW designs and manufactures precision ball bearings, and has production facilities in Europe.
