HOAC
Diamond Aircraft Industries is a manufacturer of general aviation aircraft and motor gliders, based in Wiener Neustadt, Lower Austria, Austria. It has been a subsidiary of the Chinese company Wanfeng Aviation since 2017. It is the third largest manufacturer of aircraft for the general aviation sector, and has operational facilities in both Lower Austria and Ontario, Canada, as well as further production lines operated as joint ventures in other nations, such as China. The company was founded by Austrian aircraft designer Wolf Hoffmann in 1981, at which point it was known as ''Hoffmann Flugzeugbau''. Its first aircraft, a motor glider initially known as the HK36 Dimona, became a commercial success and led to improved models and further types of aircraft derived from it. Following several changes in ownership and naming, the company received the name ''Diamond Aircraft Industries'' in 1998. By this point, Diamond was producing a range of light aircraft, including the Dimona, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diamond HK36 Super Dimona
The Diamond HK36 Super Dimona is an extensive family of Austrian low-wing, T-tailed, two-seat motor gliders that were designed by Wolf Hoffmann and currently produced by Diamond Aircraft Industries.Said, Bob: ''1983 Sailplane Directory, Soaring Magazine'', page 121. Soaring Society of America, November 1983. USPS 499-920 Design and development The series started with the Hoffmann H36 Dimona, a touring motorglider introduced in the early 1980s. The aircraft were initially produced by Hoffmann Flugzeugbau, which became HOAC Flugzeugwerk and later Diamond Aircraft Industries. Built entirely from fibreglass, the H36 family all use a Wortmann FX 63-137 airfoil. The wings feature top-surface Schempp-Hirth-style airbrakes. Optionally, the wings can be folded by two people in a few minutes to allow storage. The original H36 has wings, while the later members of the family added slightly greater span. The H36 offers a 27:1 glide ratio, while later variants improved that by one p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diamond DA20
The Diamond DV20/DA20 Katana is an Austrian-designed two-seat general aviation light aircraft. Developed and manufactured by Diamond Aircraft, it was originally produced in Austria as the DV20. The DV20 shares many features from the earlier Diamond HK36 Super Dimona. It was introduced to service during 1993. During the 1990s, production of the type was commenced at a new facility in Canada in order to meet demand for the type within the North American market. The Canadian-produced aircraft are designated as the ''DA20''. It has been a relative success on the market, having sold in excess of 1,000 aircraft by 2008 and multiple improved variants of the DA20 have been developed. Additionally, it has been further developed into the four-seat Diamond DA40 Diamond Star. Development Origins In 1981, a new company, Hoffmann Flugzeugbau, was formed in Austria with the aim of becoming a major aircraft manufacturer for general aviation purposes.Sarsfield, Kate"A shining example."

GmbH
(; ) is a type of Juridical person, legal entity in German-speaking countries. It is equivalent to a (Sàrl) in the Romandy, French-speaking region of Switzerland and to a (Sagl) in the Ticino, Italian-speaking region of Switzerland. It is an entity broadly equivalent to the private limited company (PLC) in the United Kingdom and many Commonwealth of Nations, Commonwealth countries, and the limited liability company (LLC) in the United States. The name of the GmbH form emphasizes that the owners (, also known as members) of the entity are not personally liable for the company's debts. GmbHs are considered legal persons under German, Swiss, and Austrian law. Other variations include mbH (used when the term is part of the company name itself), and gGmbH () for non-profit companies. The GmbH has become the most common corporation form in Germany because the AG (), the other major company form corresponding to a stock corporation, was much more complicated to form and operate un ...

Diamond HK 36 TTC PH-1224 Pic1
Diamond is a Allotropes of carbon, solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. Diamond is tasteless, odourless, strong, brittle solid, colourless in pure form, a poor conductor of electricity, and insoluble in water. Another solid form of carbon known as graphite is the Chemical stability, chemically stable form of carbon at Standard temperature and pressure, room temperature and pressure, but diamond is metastable and converts to it at a negligible rate under those conditions. Diamond has the highest Scratch hardness, hardness and thermal conductivity of any natural material, properties that are used in major industrial applications such as cutting and polishing tools. Because the arrangement of atoms in diamond is extremely rigid, few types of impurity can contaminate it (two exceptions are boron and nitrogen). Small numbers of lattice defect, defects or impurities (about one per million of lattice atoms) can color ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Avionics
Avionics (a portmanteau of ''aviation'' and ''electronics'') are the Electronics, electronic systems used on aircraft. Avionic systems include communications, Air navigation, navigation, the display and management of multiple systems, and the hundreds of systems that are fitted to aircraft to perform individual functions. These can be as simple as a searchlight for a police helicopter or as complicated as the tactical system for an airborne early warning platform. History The term "avionics" was coined in 1949 by Philip J. Klass, senior editor at ''Aviation Week & Space Technology'' magazine as a portmanteau of "aviation electronics". Radio communication was first used in aircraft just prior to World War I. The first Airborne radio relay, airborne radios were in zeppelins, but the military sparked development of light radio sets that could be carried by heavier-than-air craft, so that aerial reconnaissance biplanes could report their observations immediately in case they we ...

Very Light Jet
A very light jet (VLJ), entry-level jet or personal jet, previously known as a microjet, is a category of small business jets that seat four to eight people. VLJs are considered the lightest business jets and are approved for single-pilot operation. History The first small jet-powered civil aircraft, the 1950s Morane-Saulnier MS.760 Paris, has been retroactively suggested as being the first VLJ, as it seats four with a single pilot and is smaller than modern VLJs. The production of MS.760 differs from modern business jets in having a sliding canopy for cabin access rather than a door; a six-seat version with an enclosed cabin and a conventional door was canceled after a single prototype was built. Two unbuilt Cessna aircraft of the 1950s and 1960s would have met the definition of a VLJ. The first was the 407, a four-seat civil version of the T-37 jet trainer proposed in 1959; however, the 407 never progressed past the mockup stage due to insufficient customer interest. The s ...

Surveillance Aircraft
Surveillance aircraft are aircraft used for surveillance. They are primarily operated by military forces and government agencies in roles including intelligence gathering, maritime patrol, battlefield and airspace surveillance, observation (e.g. artillery spotting), and law enforcement. Surveillance aircraft usually carry limited defensive armament, if any. They do not require high-performance capability or stealth characteristics and may be modified civilian aircraft. Surveillance aircraft have also included moored balloons (e.g. TARS) and unmanned aerial vehicles (UAVs). History Pre World War I The French were the first to adopt hydrogen-filled balloons on the battlefield for reconnaissance. In the early 1790s, the French would deploy a hydrogen-filled balloon that held two soldiers: one who possessed a telescope, and the other would relay information to troops on the ground. These balloons did not cross into enemy lines; they were deployed on friendly lines for the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.
