2022年4月5日 · A short animation of a Robinson R-44 helicopter in a low G push over, resulting in a tail boom strike. #aviation #helicopter #helicoptercrash #r44 #robinson...

2024年10月21日 · Learn about all the changes to SFAR 73 affecting Robinson R22 and R44 helicopters – enhanced autorotations, low-g flight training, blade stall and more. Also, goodbye to GELL, hello to GIML!….

Enhanced training in autorotation procedures, Engine rotor RPM control without the use of the governor, Low rotor RPM recognition and recovery, and Effects of low G maneuvers and proper recovery procedures.

2023年10月19日 · The rule would revise the special federal aviation regulation (SFAR) that stipulates training and experience requirements for Robinson R22 and R44 helicopters, effectively removing the low-G dual flight instruction requirement to align with current airworthiness directives, aircraft placard requirements, and the limitations outlined in the ...

2005年4月17日 · The lateral rotation of disk creates resisting relative air flows, on top of the inertial slowness. A more artistic plot of the lift and drag distribution. A final note ------------ This phenomenon has been associated during the last decade by some people with the R22/R44. I am myself a happy R44 owner.

2009年3月12日 · As you said, a Low-G is mainly attributed to pilot inputs. Pilot moves cyclic forward abruptly which unloads the main rotor blades. The forward momentum increases the induced flow which results in a decreased AOA. Low-G is due to the increasing amount of air moving DOWN thru the rotor system, not up

2020年10月30日 · They’re not an unsafe airframe. If the tail comes off any helicopter, whether from mechanical failure or pilot error, they’ll react much the same way we see here. Any semi-rigid rotor system is susceptible to low-g pushovers and the resultant mast-bumping or tail strike if not reacted to appropriately.

2015年6月26日 · I'm a low hour student training in an R44, I try and read as much as I can, from FAA books, the POH, here, etc. Today was my first day of training on auto entries. While entering the auto, there is a clear feeling of less than 1G. A couple years ago when I did an intro flight the instructor I had did an auto and I experienced the same feeling.

‌罗宾逊R44‌是由罗宾逊直升机公司研制生的一款高性能、高可靠性直升机。 该直升机采用莱康明Q-540活塞发动机，最大功率为260马力，巡航速度可达210公里/小时，最大航程约为645公里，最大升限为4270米，适合飞行训练、航空摄影和航空护林等领域使用‌。

2005年11月16日 · How to recover from low g - stop the forward stick rate, and stop the down collective rate. This will cause the g to rise, because YOU were making it reduce when you made the aircraft maneuver.
