Production of the military-minded Tarhe yielded total units of its own beginning with the six YCHA pre-production models. He works with guys on the ground — or more likely, strapped onto a tower hundreds of feet above the ground — and together they have skycrabe fly the load accurately enough to align bolt holes.
Somewhere, Igor Sikorsky is smiling. Our Data Modules allow for quick visual reference when comparing a single entry against contemporary designs. Archived from the original on 3 June Just as an exercise in armchair piloting, imagine controlling a large flying machine, close to the ground, while it gains or loses more than 10 tons in less than a minute! As the helicopter flies at a steady 30 feet helkcopter 30 knots, the device dives under the surface and water is forced through orifices in its leading edge up through the tube and into the tank.
If necessary, in a very short time, they could be rescuing people ehlicopter on the roof of a burning high-rise, delivering an essential bulldozer, stringing cable across a canyon or transporting a small building to a remote site.
It is currently produced as the S Aircrane by Erickson Inc.
The CHB saw an increase in overall weight as well as a twin-wheeled undercarriage introduced while power was now served through PW TP turboshaft engines of 4, horsepower. The phone rang — it was my dad, and it was bad news. Aviation portal United States Army portal. But in the Crane, the left seat was almost two feet inboard of the door, and there was no way to see down and out.

The S did its job, demonstrating the usefulness of the crane idea and impressing military planners and buyers.
Retrieved 26 January I took my check ride that afternoon, and by evening I was on my way to Canada in the Bell. The aft-facing pilot feature pioneered on the S was retained, although it required an extra crew member. The rear-seater could turn his seat around and fly facing the load. In other projects Wikimedia Commons. The prototype S first flew on 9 May and was followed by two further examples for evaluation by the German armed forces.
What it has done is to fully remanufacture almost half the airframes remaining. His father, Axel, had founded the Erickson Lumber Co. The Crane has steps, like ladders, all over the airframe. The Army put them to work in Vietnam, using them to deliver artillery pieces, retrieve downed aircraft, move cargo and unload ships … and sometimes in ways Sikorsky had never envisioned.

It served as the base design for the military-minded CH “Tarhe” line as well. When we start the engines, our ground crew climbs those steps, right up there under the spinning rotors and by the jet exhaust, looking for blown hoses, leaks, anything that might give us a problem.
