Yes and Yes.So James Bombed and Jinx push the Hughes 500 Notar out of the Antonov and start it in freefall. It was more fun than the roach race in my room. So...
Without hydraulic boost, will a chopper autorotate?
Could you start one in freefall given the airloads?
Where can I get lessons?
I appreciate the legit answers. What would keep a notar machine in a straight line while autorotating? You'd think it would rotate opposite the main rotor having no counteracting tail rotor.
Aw,its just a movie. Anybody know where I can get a Star Wars speeder bike?
Yup, until you pull pitch to arrest your descent you don't need to use the anti-torque pedals.
Not quite. There is neither a fan nor a rotor in the tail. Anti-torque is handled through a slit along the tail boom creating a low pressure area on one side (the Coandă effect).Well, the TR drive shaft is still turning because it's connected to the transmission, right? Isn't the NOTAR the same except, intsead of a really long drive shaft and TR, it has a shorter shaft that drives a fan? The fan still turns so there is still thrust being generated, right?
Quite true if you are interested in generating lift. No so big a deal if not. The airflow will actually assist the start (if upright) since at flat pitch, the majority of the disc is the driven region of the blade.Please refer to most helicopter manuals that state the importance of maintaining rotor speed.
According to McDonnel Douglas it is actually a mix of what you and I are saying.Not quite. There is neither a fan nor a rotor in the tail. Anti-torque is handled through a slit along the tail boom creating a low pressure area on one side (the Coandă effect).
Yup, until you pull pitch to arrest your descent you don't need to use the anti-torque pedals.
Actually, it is feasible. However, the stars would have to align just right.Aside from the fact you would disintegrate into a massive mess of metal and plastic when falling vertically with no Nr... no, it would not work.
Please refer to most helicopter manuals that state the importance of maintaining rotor speed. Good movie... totally fake helo ending.
I guess so. Geez its been so long that I'd forgotten!Actually, the torque from the autorotating main rotor feeds back into the main transmission, and the friction in the drivetrain actually drives the airframe out of balance in the opposite direction from powered flight. To stay in trimmed flight and reduce your rate of descent, you have to feed in opposite pedal. It happens pretty naturally, the pilot is going to trim to balanced flight as a matter of habit, but there is a pedal input required.
