Homebuilt aircraft planes constructed by persons for whom this is not a professional activity

Homebuilt aircraft, also known as amateur-built aircraft or kit planes, are constructed by persons for whom this is not a professional activity. These aircraft may be constructed from "scratch", from plans, or from assembly kits.

Helicopter Type of rotor craft in which lift and thrust are supplied by rotors

A helicopter, or chopper, is a type of rotorcraft in which lift and thrust are supplied by rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward, and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of VTOL aircraft cannot perform.

Marianna, Florida City in Florida, United States

Marianna is a city in Jackson County, Florida, United States. The population was 6,102 at the 2010 census. In 2018 the estimated population was 7,091. It is the county seat of Jackson County and is home to Chipola College. The official nickname of Marianna is "The City of Southern Charm".

The design is reminiscent of a small-scale Bell 47 helicopter. In fact, the helicopter was originally called the Baby Belle, but Bell Helicopters objected and the name was changed to Safari. [4]

Bell 47 family of light helicopters

The Bell 47 is a single rotor single engine light helicopter manufactured by Bell Helicopter. It was based on the third Bell 30 prototype, which was the company's first helicopter designed by Arthur M. Young. The 47 became the first helicopter certified for civilian use on 8 March 1946. More than 5,600 Bell 47s were produced, including those under license by Agusta in Italy, Kawasaki Heavy Industries in Japan, and Westland Aircraft in the United Kingdom. The Bell 47J Ranger is a modified version with a fully enclosed cabin and tail boom.

Design

The Safari is a two-seat light helicopter with a bubble canopy, a two-bladed main rotor and a skid landing gear. The aircraft structure consists predominantly of welded 4130 chromoly steel tubing. The kit provides the main and tail rotors, rotor hubs, transmission, engine, cockpit and tailboom completed. Builder construction is largely assembly. [5]

Bubble canopy

A bubble canopy is a canopy made without bracing, which attempts to provide 360° vision to the pilot. Bubble canopy designs vary. Some, like on later versions of the F4U Corsair, are built into the upper rear fuselage, while others, like the canopy of the P-51D Mustang and most modern fighter aircraft, are built flush with the fuselage, providing unobstructed rear visibility.

41xx steel is a family of SAE steel grades, as specified by the Society of Automotive Engineers (SAE). Alloying elements include chromium and molybdenum, and as a result these materials are often informally referred to as chromoly steel. They have an excellent strength to weight ratio and are considerably stronger and harder than standard 1020 steel, but are not easily welded, requiring thermal treatment both before and after welding to avoid cold cracking.

Engine options over time have included the 160 hp (119 kW) Lycoming O-320-B2B, 180 hp (134 kW) Lycoming O-360-C2C, the 160 hp (119 kW) Superior XP320 and the 180 hp (134 kW) XP360 engines. [6]

Lycoming O-320 family of flat-four piston aircraft engines

The Lycoming O-320 is a large family of 92 different naturally aspirated, air-cooled, four-cylinder, direct-drive engines commonly used on light aircraft such as the Cessna 172 and Piper Cherokee. Different variants are rated for 150 or 160 horsepower. As implied by the engine's name, its cylinders are arranged in horizontally opposed configuration and a displacement of 320 cubic inches (5.24 L).

Lycoming O-360 flat-four piston aircraft engine family by Lycoming

The Lycoming O-360 is a family of four-cylinder, direct-drive, horizontally opposed, air-cooled, piston aircraft engines. Engines in the O-360 series produce between 145 and 225 horsepower, with the basic O-360 producing 180 horsepower.
