Kaman Aircraft
Kaman Corporation 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, a major distributor and manufacturer of musical instruments and accessories. History Charles Kaman founded the company in December 1945 with $2,00 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Private Company
A privately held company (or simply a private company) is a company whose Stock, shares and related rights or obligations are not offered for public subscription or publicly negotiated in their respective listed markets. Instead, the Private equity, company's stock is offered, owned, traded or exchanged privately, also known as "over-the-counter (finance), over-the-counter". Related terms are unlisted organisation, unquoted company and private equity. Private companies are often less well-known than their public company, publicly traded counterparts but still have major importance in the world's economy. For example, in 2008, the 441 list of largest private non-governmental companies by revenue, largest private companies in the United States accounted for $1.8 trillion in revenues and employed 6.2 million people, according to ''Forbes''. In general, all companies that are not owned by the government are classified as private enterprises. This definition encompasses both publ ...

Blackburn Aircraft
Blackburn Aircraft Limited was a British aircraft manufacturer from 1914 to 1963 that concentrated mainly on naval and maritime aircraft. History Blackburn Aircraft was founded by Robert Blackburn (aviation pioneer), Robert Blackburn and Jessy Blackburn, who built his first aircraft in Leeds in 1908 with the company's Olympia Works at Roundhay opening in 1914. The Blackburn Aeroplane & Motor Company was created in 1914 and established in a new factory at Brough, East Riding of Yorkshire, Brough, East Riding of Yorkshire in 1916. Robert's brother Norman Blackburn (aviation pioneer), Norman Blackburn later became managing director. Blackburn acquired the Cirrus aero engines, Cirrus-Hermes Engineering company in 1934, beginning its manufacture of aircraft engines. However an updated range of engines was under development and Blackburn wanted to wait until it was established before giving its name to them, so Cirrus Hermes Engineering was retained as a separate company for the time ...

Tip Jet
A tip jet is a jet nozzle at the tip of some helicopter rotor blades, used to spin the rotor, much like a Catherine wheel firework. Tip jets replace the normal shaft drive and have the advantage of placing no torque on the airframe, thus not requiring the presence of a tail rotor. Some simple monocopters are composed of nothing but a single blade with a tip rocket. Tip jets can use compressed air, provided by a separate engine, to create jet thrust. Other types use a system that functions similarly to the afterburner (reheat) on a conventional jet engine, except that instead of reheating a gas jet, they serve as the primary heater, creating greater thrust than the flow of pre-compressed air alone; the best description of this is ''thrust augmentation''. Other designs includes ramjets or even a complete turbojet engine. Some, known as ''rocket-on-rotor'' systems, involve placing rockets on the tips of the rotor blades that are fueled from a tank. If the helicopter's engine fail ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

V/STOL
A vertical and/or short take-off and landing (V/STOL) aircraft is an airplane able to takeoff and landing, take-off or land vertically or on short runways. VTOL, Vertical takeoff and landing (VTOL) aircraft are a subset of V/STOL craft that do not require runways at all. Generally, a V/STOL aircraft needs to be able to hover. Helicopters are not considered under the V/STOL classification as the classification is only used for aeroplanes, aircraft that achieve lift (force) in forward flight by planing the air, thereby achieving speed and fuel efficiency that is typically greater than the capability of helicopters. Most V/STOL aircraft types were experiments or outright failures from the 1950s to 1970s. V/STOL aircraft types that have been produced in large numbers include the F-35B Lightning II, Harrier jump jet, Harrier and V-22 Osprey. A rolling takeoff, sometimes with a ramp (Aircraft ski-jump, ski-jump), reduces the amount of thrust required to lift an aircraft from the gro ...

HH-43 Huskie
The Kaman HH-43 Huskie is a helicopter developed and produced by the American rotorcraft manufacturer Kaman Aircraft. It is perhaps most distinctive for its use of twin intermeshing rotors, having been largely designed by the German aeronautical engineer Anton Flettner. First flown on 21 April 1953, the HH-43 went into production and was operated by several military air services, including the United States Air Force, the United States Navy and the United States Marine Corps. It was primarily intended for use in aircraft firefighting and rescue in the close vicinity of air bases, but was extensively deployed during the Vietnam War. It was used as a search and rescue platform, having often been enhanced with makeshift modification and new apparatus to better suit the tropical conditions. The HH-43 was also exported to several other countries and sold commercially. It set several aviation records in its class, and was the first helicopter to experiment with twin-turbine engines.

Unmanned Aerial Vehicle
An unmanned aerial vehicle (UAV) or unmanned aircraft system (UAS), commonly known as a drone, is an aircraft with no human pilot, crew, or passengers onboard, but rather is controlled remotely or is autonomous.De Gruyter Handbook of Drone Warfare; 2024. e-ISBN (PDF) 978-3-11-074203-9.H. Pan; M. Zahmatkesh; F. Rekabi-Bana; F. Arvin; J. HuT-STAR: Time-Optimal Swarm Trajectory Planning for Quadrotor Unmanned Aerial Vehicles IEEE Transactions on Intelligent Transportation Systems, 2025. UAVs were originally developed through the twentieth century for military missions too "dull, dirty or dangerous" for humans, and by the twenty-first, they had become essential assets to most militaries. As control technologies improved and costs fell, their use expanded to many non-military applications. These include aerial photography, area coverage,F. Rekabi-Bana; Hu, J.; T.

Gas Turbine
A gas turbine or gas turbine engine is a type of Internal combustion engine#Continuous combustion, continuous flow internal combustion engine. The main parts common to all gas turbine engines form the power-producing part (known as the gas generator or core) and are, in the direction of flow: * a rotating gas compressor * a combustor * a compressor-driving turbine. Additional components have to be added to the gas generator to suit its application. Common to all is an air inlet but with different configurations to suit the requirements of marine use, land use or flight at speeds varying from stationary to supersonic. A propelling nozzle is added to produce thrust for flight. An extra turbine is added to drive a propeller (turboprop) or ducted fan (turbofan) to reduce fuel consumption (by increasing propulsive efficiency) at subsonic flight speeds. An extra turbine is also required to drive a helicopter rotor or land-vehicle transmission (turboshaft), marine propeller or electric ...
