The 60 year anniversary of -THE- "barrel roll"...
that truly launched us into the passenger jet age. A retired Boeing engineer told me that Tex got suspended from flying for a couple of months over this stunt. (www.seattletimes.com) 更多...Sort type: [Top] [Newest]
Isn't it strange that in 60 years everyone who has had the public ear to comment on this famous prototype B-707 maneuver doesn't know the difference between a barrel roll and an aileron roll? It takes a bit of flying skill to do a fair barrel roll, which this wasn't. And it wasn't even a good aileron roll. Tex should have picked the nose up a bit with a little speed and rolled it on the longitudinal without 'dishing out'. This maneuver was more a tribute to Boeing engineers than some poorly executed and simple "stunt". Sorry folks. Having some late-life buyers remorse with news hype. Macidull (Hammer), Motpoll.com.
Very True... The Aileron Roll is not a 1g Maneuver like the Barrel Roll and the the 707 could not do an aileron roll because all of its engines would have shut down over Oil and Fuel Starvation.
Right. Aileron roll is not a 1g Maneuver like a Barrel Roll. Obviously the 707 could do an aileron roll without fuel starvation on any of its engines, as that is what it did. Could it be that this is because fuel injection operates differently than G-dependent carburetors, and engines rarely 'fail' instantly from low oil pressure? The last time this was a problem involved the first carburetor RR Merlin equipped Spitfires against the ME 109s during the Battle of Britain. A zero-G aileron roll in this case would not have been a problem with fuel injected into a turbojet burner section as would be the case with any float-valve gravity-dependent fuel system.
Correction.. .He could not go an Aileron Roll because it was not 1G, The Barrel Roll is exactly 1G and is why the 707 can do it... The reason it cannot do the aileron roll is because of Fuel and Oil Starvation of the engines.
I think that it could of done any type of roll it wanted. The Air Force and some private organizations have been flying Vomit Comets for decades. Some types are 727s and 707s that have not been modified except for special interiors. I think a 707 was used to film the weightless scenes from "Apollo 13" that required hours of Zero G or microgravity 30 or 45 seconds at a time. My son got a ride in one and said it was an absolute blast.
The weightless scenes were not inverted at anytime and that is what causes the problem... The Vomit Commit even though simulates 0G, it is not negative G and that is why the barrel roll works and the aileron roll would not.
