The wings are identical to the Bearhawk 4-Place Model B, employing the same Riblett 30-413.5 airfoil [5] and mounting flaps. [4] The aircraft's recommended engine power range is 250 to 315 hp (186 to 235 kW) and standard engines used include the 250 hp (186 kW) Lycoming O-540 , although the recommended engine is the 315 hp (235 kW) Lycoming IO ...
The Bearhawk was designed in the early 1990s [5] as a personal project by Barrows to carry aircraft engines for delivery as freight. It features a strut-braced high-wing, a four-seat enclosed cabin that is 42.5 in (108 cm) wide and accessed by doors, fixed conventional landing gear and a single engine in tractor configuration.
Bearhawk Model 5. Barrows is the designer of the Bearhawk Patrol, Companion, 4-Place, and Model 5 light aircraft, [3] as well as the Bearhawk LSA light-sport aircraft. [4]Prior to designing the first aircraft in the Bearhawk series, the 4-Place, Barrows designed and built a STOL high wing plane called the Grasshopper and an aerobatic biplane. [5]
Two points on a fuselage at waterline 100/fuselage station 93 and waterline 101/fuselage station 276. Lofting coordinates are used for aircraft body measurements. The system derives from the one that was used in the shipbuilding lofting process, with longitudinal axis labeled as "stations" (usually fuselage stations, frame stations, FS), transverse axis as "buttocks lines" (or butt lines, BL ...
[1] [4] In 2015 a quick-build kit was introduced at the U.S Sport Aviation Expo. [5] The aircraft fuselage is fabricated from welded 4130 steel tubing covered in doped aircraft fabric. The aluminum structure wing, covered in flush riveted aluminum sheet, employs a new Harry Riblett-designed airfoil and does not have flaps. The wing is supported ...
The Barrows Bearhawk Patrol is a two-seat aircraft, that was designed to meet United States homebuilt aircraft category requirements. It was developed from the four-seat Barrows Bearhawk. [1] [2] [3] A development of the Patrol is the Bearhawk Companion, a two seat in side-by-side configuration variant. [4]

Diagram of a typical gas turbine jet engine. Air is compressed by the compressor blades as it enters the engine, and it is mixed and burned with fuel in the combustion section. The hot exhaust gases provide forward thrust and turn the turbines which drive the compressor blades. 1. Intake 2. Low pressure compression 3. High pressure compression ...
