MV-22 crashes in Hawaii

Of coarse..didnt you know there are no dual rotor aircraft around so deskjockey journos and experts (drips under pressure) can make up anything they want to validate their credentials...

Sounds like media bullsh*t to me! They also believe that aircraft fly by "pure f**king magic" and when the PFM generator fails the plane crashes.

Along with the journo trying to make it sound like only tilt-rotors experience VRS as opposed to a trait shared by all rotary-wing aircraft...

If they can't get the aerodynamics of an airplane right they sure to hell can't understand rotary wing flight. Even some helicopter pilots don't understand fully the dynamics of helicopters.

Tandem rotor helicopters have different dynamics than single rotor helicopters. Tandem helos like the Chinook need to have stability augmentation systems (SAS) to overcome the tendencies to fly sideways. A side-by-side rotor aircraft like the Osprey have unique characteristics that is new to me so I'm not an expert.

The news people are little more that talking heads that's why the public is so clueless! If they reported details and facts they would bore the viewers and they wouldn't have an audience. They resort to the PFM approach to reporting and scare the audience.

Well, in their defense, just as with the bumblebee, science can't really explain how helicopters fly. They're nothing but a few thousand parts flying in very close formation.

Calpoly has a video of why bumble bee fly. They did the study for DARPA's micro bot testing. I don't have the education to explain it but here goes. The upper wing causes small air vortices and the lower wing pushes against them causing lift.

Rotary wing dynamics is understood but it takes only the top 10% of the aero engineers to build a helicopter. They are few and far between. Even Igor Sikorsky had an army of engineers for the V-300 and Bell had a true genius in Art Young. Art wasn't an engineer but a physicist, IIRC.

I thought I understood RW dynamics until I took up RC helicopters. I was trying to apply full size rules to a 1/6 size aircraft and was it ever humbling.

Unfortunately a second marine succumbed to his wounds today.

I was trying to lay the sarcasm on pretty thick there.

Yeah, the dynamics of flying from full scale, in the cockpit flying to R/C flying are wildly different.

That sucks to hear.

Respect to both...

The aircraft spent 45 seconds in brownout conditions before both engines suffered reduced power and the left engine suffered a compressor stall apparently. The right didn't have enough power to keep them airborne because of dust and dirt in the engine.

You would think you would tell that something is wrong a lot sooner than 45 seconds.Thats an eternity...

Marine Aviation had set 60 seconds as the maximum amount of time you could hover in brownout conditions.
