The Boeing Osprey Finally gets off the Ground

07/19/2006 7:46 AM

Interesting CNN video report about the Osprey a hybrid plane / helicopter designed for use by the US Marine Corp. Over its twenty years in development, the Osprey has had many problems including cost overruns and fatal crashes. It was recently demonstrated at an airshow at Farnborough Airport in the UK.

Boeing hopes to see the aircraft deployed in Iraq sometime next year, although the report made me a little leery of this taking place. One of the two Osprey's flying to the show had to land in Iceland due to mechanical problems; and if you listen closely to the reporter, he is told not to grab any wires when the plane is flying because this could pull out vital circuits! Call me crazy, but that doesn't sound like a plane that's ready for military deployment. I hope these two were stripped test models and that hardened versions will be made available for combat duty.

New Mexico

07/19/2006 1:42 PM

According to Boeing, "The U.S. Air Force Special Operations Command took delivery of the first CV-22 configured for operational missions on March 1, 2006, and will begin training at Kirtland Air Force Base, N.M. this year." New Mexico is a great proving ground for desert warfare; however, Kirtland AFB borders residential neighborhoods in Albuquerque. God forbid an Osprey goes down.

Each month a new $160 million V-22 comes off the production line and is rolled into storage since its unsafe to fly. Why? Wings don't tilt, so robbing the aircraft of a large proportion of lift, and inducing stall, usually on one side only, causing the craft to tilt alarmingly in high speed decents. 2000ft is required to recover the stall, and most combat operations are conducted under 1000feet.Hmm, get me a helicopter.

Earlier this year one of these things was buzzing around Worcester Airport in MA. What a racket it made! First I though a biker gang was rolling through town, but it kept getting closer and louder so I went outside to check things out. There it was hovering directly over my folk's neighbor's house. It sounded similar to a commercial turboprop running wide open with its props fully feathered, only much louder. Crazy to hear how dangerous these things are and the blatant disregard of whomever okayed it to fly over residential areas. I think it had to do with the talk of closing of two local AFBs and the potential solution to use Worcester airport as a military training facility. Someone wanted to disturb the residents to gain protest. If this was the case, that thing was the perfect way to make it happen.

Boeing has a patent that is supposed to correct the aerodynamic problems with the V-22. The solution requires counter rotating props on each side (4 sets). Depending on which direction the designer selects, there are control issues that arise in certain flight regimes due to flow interations with the wind. Tilting the wing would make other problems. The patent explains this.

How far is it from a patent to actuality? Again, the term good money after bad can be heard in the background. How long would Boeing, as a profit making company, continue with this project if they had to pay all the bills?
