Robinson 44

Robinson 44

The R44 is a single-engined helicopter with a semi-rigid two-bladed main rotor, a two-bladed tail rotor and a skid landing gear. It has an enclosed cabin with two rows of side-by-side seating for a pilot and three passengers. Tail rotor direction of rotation on the R44 is reversed compared to the R22 for improved yaw control authority. On the R44 the advancing blade is on the bottom.

Designed during the 1980s by Frank Robinson and his staff of engineers, the R44 first flew on 31 March 1990. The R44 Astro was awarded an FAA Type Certificate in December 1992, with the first deliveries taking place in January 1993. In January 2000, Robinson introduced the Raven with hydraulically assisted controls and adjustable pedals. In July 2002, Robinson introduced the Raven II featuring a more powerful, fueal-injected engine and wider blades, allowing a higher gross weight and improved altitude performance.

Robinson produced 186 R44s in 2014.

During November 2015 Robinson announced the Cadet, a Raven I with a cargo area instead of the two back seats, a slightly less powerful engine and a more efficient muffler.
