Aero Dynamics Sparrow Hawk
The Aero Dynamics Sparrow Hawk MK II is an American homebuilt, two seater, single-engine, pusher monoplane, manufactured by Aero Dynamics Limited. It was designed by former Boeing design engineer Charles "Chuck" Herbst. Design and development The Sparrow Hawk is a twin boom, twin fin, ultralight aircraft built with mixed construction materials most notably including Kevlar, carbon fiber and polyurethane foam. It uses a Rotax 532 two-stroke aircraft engine in pusher configuration. It employs a cantilever, shoulder wing, fixed landing gear and a two-seat enclosed cockpit. In 2022, Sparrow Hawk Aviation Ltd announced that they had plans to redesign and improve the Sparrow Hawk, though no redesigns have been made to the aircraft design yet. Operational history The Sparrow Hawk had its official public debut in July 1985 at the EAA Annual Convention and Fly-In, as two Sparrow Hawks, registered as N5793F and N5832M, attended.

Pusher Configuration
In an aircraft with a pusher configuration (as opposed to a tractor configuration), the propeller(s) are mounted behind their respective engine(s). Since a pusher propeller is mounted behind the engine, the drive shaft is in compression in normal operation. Pusher configuration describes this specific (propeller or ducted fan) thrust device attached to a craft, either aerostat (airship) or aerodyne (aircraft, WIG, paramotor, rotorcraft) or others types such as hovercraft, airboat and propeller-driven snowmobiles. "Pusher configuration" also describes the layout of a fixed-wing aircraft in which the thrust device has a pusher configuration. This kind of aircraft is commonly called a pusher. Pushers have been designed and built in many different layouts, some of them quite radical. History The rubber-powered "Planophore", designed by Alphonse Pénaud in 1871, was an early successful model aircraft with a pusher propeller. Many early aircraft (especially biplanes) were ...

1980s United States Ultralight Aircraft
__NOTOC__ Year 198 (CXCVIII) was a common year starting on Sunday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sergius and Gallus (or, less frequently, year 951 ''Ab urbe condita''). The denomination 198 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Shoulder-wing Aircraft
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplanes, which have multiple planes. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, the weight reduction allows it to fly slower a ...

Aircraft Engine
An aircraft engine, often referred to as an aero engine, is the power component of an aircraft propulsion system. Most aircraft engines are either piston engines or gas turbines, although a few have been rocket powered and in recent years many small UAVs have used electric motors. Manufacturing industry In commercial aviation the major Western manufacturers of turbofan engines are Pratt & Whitney (a subsidiary of Raytheon Technologies), General Electric, Rolls-Royce, and CFM International (a joint venture of Safran Aircraft Engines and General Electric). Russian manufacturers include the United Engine Corporation, Aviadvigatel and Klimov. Aeroengine Corporation of China was formed in 2016 with the merger of several smaller companies. The largest manufacturer of turboprop engines for general aviation is Pratt & Whitney. General Electric announced in 2015 entrance into the market.

Two Stroke
A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a power cycle with two strokes (up and down movements) of the piston during one power cycle, this power cycle being completed in one revolution of the crankshaft. A four-stroke engine requires four strokes of the piston to complete a power cycle during two crankshaft revolutions. In a two-stroke engine, the end of the combustion stroke and the beginning of the compression stroke happen simultaneously, with the intake and exhaust (or scavenging) functions occurring at the same time. Two-stroke engines often have a high power-to-weight ratio, power being available in a narrow range of rotational speeds called the power band. Two-stroke engines have fewer moving parts than four-stroke engines. History The first commercial two-stroke engine involving cylinder compression is attributed to Scottish engineer Dugald Clerk, who patented his design in 1881. However, unlike most later two-st ...

Cranfield Airport
Cranfield Airport is an airfield just outside the village of Cranfield, in Bedfordshire, England. It is south-west of Bedford and east of Milton Keynes. It was originally a World War II aerodrome, RAF Cranfield. It is now used for business aviation, private flights, and for research and development activities. History RAF Cranfield was built by John Laing & Son on of farmland acquired by the Air Ministry in 1935 as Britain re-armed to face the growing threats on the continent. It was formally opened on 1 June 1937 and initially became the base for No. 62 Squadron RAF and No. 82 Squadron RAF of No. 1 (Bomber) Group, flying the already obsolete Hawker Hind biplanes. Both squadrons converted to Blenheim 1s in 1938. 62 Squadron was moved to Singapore in August 1939 where it was destroyed by the invading Japanese Imperial forces. RAF Cranfield's grass airstrip was replaced with three hardened runways in the winter of 1939 and spring of 1940 and became a target for enemy acti ...
