History

The R44, designed during the 1980s by company president Frank Robinson and his staff of engineers, first flew on March 31, 1990. It was awarded an FAA Type Certificate in December 1992, with the first deliveries taking place shortly thereafter. Originally, the R44 Astro was the main production model, but was dropped in favour of the hydraulically-assisted R44 "Raven" in 2000. The Raven II model (2002 onwards) used a fuel injected engine, tuned induction, Optional Air conditioning, Optional Night VFR, 28V electrical system, and extended-chord blades for increased performance.

Clipper

An Astro, Raven or Raven II, modified with pop-out or fixed utility floats, for water-borne operations. The pop-out floats, when activated, inflate in approximately 1.3 seconds from a gas supply tank under the passenger seat. The floats are deployed via a lever with an arming pin and breakaway shear pin on the collective. The fixed utility floats are kept inflated allowing for routine water landings. In Clipper with fixed floats, typically only fresh water landings are carried out to avoid drawing salt water spray up into the engine compartment. Pop-out floats are only used for emergency water landings.


Police

A law enforcement modification of one of the main production models, with a belly-mounted searchlight, a nose gimbal FLIR system, and enlarged windows. Due to weight limitations, the right-rear seat is replaced with an aluminum panel and the helicopter is usable only as a 3-seat aircraft when equipped as a Police variant. A forward looking infrared (FLIR) system is a camera that takes pictures using the infrared portion of the electromagnetic spectrum. ...
