Raptor Aircraft Raptor
The Raptor was a four to five-seat single-engined canard-wing homebuilt light aircraft, whose prototype was under development by Raptor Aircraft of Ball Ground, Georgia, United States. The Raptor's tricycle landing gear was fully retractable, and the streamlined pressurized airframe was to be optimized for a fast cruising speed at high altitudes. The aircraft was intended to be supplied in kit form for amateur construction. The aircraft's designer is Australian Peter Muller, whose design goals were to provide a fast, spacious aircraft with IFR capability. Muller intended that the kit would be sold "at cost". The prototype made its first substantive flight on 10 October 2020. During a ferry flight on 6 August 2021 the Raptor prototype crashed in a cornfield, suffering substantial damage. Subsequently, Muller announced that development of the Raptor would end and the company would move onto developing a derivative design, the Raptor Aircraft Raptor NG. Design and develo ...

Escrow
An escrow is a contractual arrangement in which a third party (the stakeholder or escrow agent) receives and disburses money or property for the primary transacting parties, with the disbursement dependent on conditions agreed to by the transacting parties. Examples include an account established by a broker for holding funds on behalf of the broker's principal or some other person until the consummation or termination of a transaction; or, a trust account held in the borrower's name to pay obligations such as property taxes and insurance premiums. The word derives from the Old French word , meaning a scrap of paper or a scroll of parchment; this indicated the deed that a third party held until a transaction was completed. Types Escrow generally refers to money held by a third party on behalf of transacting parties. It is mostly used regarding the purchase of shares of a company. It is best known in the United States in the context of the real estate industry (specifically in mor ...

General Aviation
General aviation (GA) is defined by the International Civil Aviation Organization (ICAO) as all civil aviation aircraft operations with the exception of commercial air transport or aerial work, which is defined as specialized aviation services for other purposes. However, for statistical purposes ICAO uses a definition of general aviation which includes aerial work. General aviation thus represents the "private transport" and recreational components of aviation. Definition The International Civil Aviation Organization (ICAO) defines civil aviation aircraft operations in three categories: General Aviation (GA), Aerial Work (AW) and Commercial Air Transport (CAT). Aerial work operations are separated from general aviation by ICAO by this definition. Aerial work is when an aircraft is used for specialized services such as agriculture, construction, photography, surveying, observation and patrol, search and rescue, and aerial advertisement. However, for statistical purposes ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Constant-speed Propeller
In aeronautics, a variable-pitch propeller is a type of propeller (airscrew) with blades that can be rotated around their long axis to change the blade pitch. A controllable-pitch propeller is one where the pitch is controlled manually by the pilot. Alternatively, a constant-speed propeller is one where the pilot sets the desired engine speed ( RPM), and the blade pitch is controlled automatically without the pilot's intervention so that the rotational speed remains constant. The device which controls the propeller pitch and thus speed is called a propeller governor or constant speed unit. Reversible propellers are those where the pitch can be set to negative values. This creates reverse thrust for braking or going backwards without the need to change the direction of shaft revolution. Some aircraft have ground-adjustable propellers, however these are not considered variable-pitch. These are typically found only on light aircraft and microlights. Purpose When an aircraft is ...

Audi
Audi AG () is a German automotive manufacturer of luxury vehicles headquartered in Ingolstadt, Bavaria, Germany. As a subsidiary of its parent company, the Volkswagen Group, Audi produces vehicles in nine production facilities worldwide. The origins of the company are complex, going back to the early 20th century and the initial enterprises ( Horch and the ''Audiwerke'') founded by engineer August Horch (1868–1951); and two other manufacturers ( DKW and Wanderer), leading to the foundation of Auto Union in 1932. The modern Audi era began in the 1960s, when Auto Union was acquired by Volkswagen from Daimler-Benz. After relaunching the Audi brand with the 1965 introduction of the Audi F103 series, Volkswagen merged Auto Union with NSU Motorenwerke in 1969, thus creating the present-day form of the company. The company name is based on the Latin translation of the surname of the founder, August Horch. , meaning "listen", becomes in Latin. The four rings of the Audi lo ...

Carbon Fibre
Carbon fiber-reinforced polymers (American English), carbon-fibre-reinforced polymers (Commonwealth English), carbon-fiber-reinforced plastics, carbon-fiber reinforced-thermoplastic (CFRP, CRP, CFRTP), also known as carbon fiber, carbon composite, or just carbon, are extremely strong and light fiber-reinforced plastics that contain carbon fibers. CFRPs can be expensive to produce, but are commonly used wherever high strength-to-weight ratio and stiffness (rigidity) are required, such as aerospace, superstructures of ships, automotive, civil engineering, sports equipment, and an increasing number of consumer and technical applications. The binding polymer is often a thermoset resin such as epoxy, but other thermoset or thermoplastic polymers, such as polyester, vinyl ester, or nylon, are sometimes used. The properties of the final CFRP product can be affected by the type of additives introduced to the binding matrix (resin). The most common additive is silica, but other addit ...
