The CL-227 Sentinel is a highly regarded part of the NATO inventory, and is regularly used on military exercises in the United Kingdom and elsewhere, day or night. Bombardier's Canadair Defence Systems Division produced an early version called the Peanut as far back as 1978.
The CL-227 is a remotely controlled helicopter with a turbine engine driving a pair of co-axial counter-rotating rotors. A successful naval develoment was completed to demonstration stage in 1992.
The Sentinel is roughly 1.8m tall, standing on four castered legs. Support vehicles include a flatbed pickup transporter with winch and launch platform, and a control / communication van, each with utility trailers. The Sentinel has also been deployed on USS Doyle for Arctic trials, operating from the helicopter deck.

there is a video on YouTube: CL-227 Sentinel "Flying Peanut"

I spent several years working on the electromechanical actuation control system that controlled the blade pitch. The system worked well enough, but I recall only a handful of systems were built.

I conducted a test and evaluation of this aircraft for the the US Army for the role of battle damage assessment looking for damage to a runway after an air strike. The idea was to determine precisely where the craters were located and if there was any unexploded ordinance that might be present on or around the airfield. Then the Army core of engineers and UXO personnel could come in an do basic repairs and clean up to get a minimum operating air strip back up in minimum time. Although it demonstrated significant capability, it never went into production for this purpose and was closely followed by a new improved VTOL replacement, the CL-327. The 227 was build by Canidair and the 327 by Bombardier. The Cl-227 was called the flying peanut for obvious reasons.

What a tragedy this craft was not used as the development platform for heavy duty commercial drones. Like the CF105 Arrow and the Hydrofoil, our engineers did their stuff only to have it canned by visionless leadership. Reminds us of Henry Ford's banker, who regarded the automobile as a passing fad!
"The CL-227 Sentinel is a highly regarded part of the NATO inventory, and is regularly used on military exercises..." This is utter bullshit. It never progressed beyond flight trials; no customer ever paid for one, and it was never used on active service.

I searched for more info but there was no results.

R Elias, you're not looking in the right places, obviously. I have seen several photos of this unit in active service. The easiest way to see it is by viewing photos of naval vessels; you'll see the CL-227 often enough if you look.

really I am concerned for this helicopter , but I think it is not true since there is no videos or more pictures on the internet, I searched for more info but there was no results.
Do you have any comments concerning this aircraft ?
