No cyclic, swash plates, tail rotor etc is all great but if the engine quits, the belt breaks or anything else fails, you are history in this thing. |

Exactly what I was thinking. :-o
Notice they try to placate the ignorant by saying that they're working on a "ballistic emergency chute." As Stu points out, if you're low enough to not need autorotative capabilities, you're not going to be anywhere near high enough for a ballistic emergency chute to do you any good either. No thanks! Steve R. "Stuart & Kathryn Fields" wrote in message ... Lawn Dart comes to mind with the designs that ignore the need for autorotation. The claim that low altitude helicopters have little benefit from autorotation is false. I've seen autos done from 40' agl and 40mph. I asked Airscooter what was available to the pilot at 40 and 40 and got the same kind of answer. If the Airscooter engine stops, the fixed pitch of the blades will cause the rotor to slow quickly and you will be in instant ka ka. I wouldn't think of one of these birds until I saw an engine out demonstrated by their test pilot. -- Stu Fields Baby Belle driver www.vkss.com "JohnO" wrote in message oups.com... boB wrote: Shiver wrote: http://www.airscooter.com/pages/airscooter_main.htm I Want One - I Want One - I Want One http://www.airscooter.com/pages/airs...edia_files.htm I Want One - I Want One - I Want One Me too.... right up until I read this in the FAQ: "Question: Does the AirScooter auto-rotate?

are turning, where would you connect the chute? "Steve R" wrote in message ...

You know, ballistic chute and rotor craft really just don't go together. I mean what's worse, being a lawn dart, or getting diced, sliced and julienned? At least in the former there's only one piece left to find and put in the casket! |

From what I remember reading in gyro circles, one group was looking at
mounting the chute on top of the rotor hub, attached via some kind of turn buckle. "Might" be a good idea but no one was brave enough to try it out. The only kit manufacturer that I know of that offers a ballistic chute on their gyro is Air Command. It's been a while since I've looked at their web site (www.aircommand.com) so I checked and a search showed that they offer a ballistic chute option on their two place machines. The one I saw for real was mounted below the gyro so if you ever set it off, you're going to be coming to the ground, "inverted." :-o I'm not sure I like that idea but it may be way better than the alternative. Again, I don't know if anyone's tried this yet. FWIW, Fly Safe, Steve R. "Ron Snipes" wrote in message om... So would the chute be attached above the Jesus Nut?

"Might" be a good idea but no one was brave enough to try it out. probably a bad idea on a gyro. Weight above the gimbal head plays with flight control. The only kit manufacturer that I know of that offers a ballistic chute on their gyro is Air Command. It's been a while since I've looked at their web site (www.aircommand.com) so I checked and a search showed that they offer a ballistic chute option on their two place machines. The one I saw for real was mounted below the gyro so if you ever set it off, you're going to be coming to the ground, "inverted." Larry Neal developed that, I believe, when he was working with AC (he also centreline-thrusted their machines). Larry is now marketing his own line of gyros, including one that's roadable as a motorcycle. He promises a ballistic chute as a future option. The way the Air Command chute works is in two stages, in stage one it hangs you inverted, then when the rotation of the rotors is arrested, you pull handle #2, releasing the low-down attach point, and you drop around to normal orientation. No one has ever done it for real, and it has not been tested AFAIK with models, let alone full size. In theory it would work if everything went well and the pilot was conscious throughout. You'd probably want to consider a possible inverted landing at about 20-22 fps and construct an appropriate roll structure. A Spanish company that makes copies of the BRS chutes (under the "we're too small to be worth suing" licence apparently -- BRS are a bit cheesed about it) has installed some on gyros. I have seen this installation on an RAF and it is conceptually identical to Larry's Air Command install. I have heard that the Galaxy chute company, which I believe is Czech, has a gyro chute but haven't seen how they do it. I doubt the total number of ballistic chutes on rotorcraft worldwide reaches double digits. I know none has ever been deployed in angre. There is some talk that one of Larry's current dealers will assist in developing the chute including full size tests. A test pilot would bail out of a ballasted & instrumented gyro at altitude and then the ballistic would be fired by remote control. Win or lose, this would gather useful data, and it would be safe as the pilot would be down and away before the chute was fired. The tests will be done overseas where regulators are more cooperative and less timid than in the USA. :-o I'm not sure I like that idea but it may be way better than the alternative. Again, I don't know if anyone's tried this yet. Ballistic chutes have been saving lives for two decades on ULs, almost as long on experimentals, for five years on certified aircraft, and they're coming on jets. They would be big lifesavers if they could be made to work on gyroplanes, as the most typical gyroplane fatal is a tumble from around pattern altitude. They would also have potential for life savings on helicopters -- look at the double-fatal cop crash in Michigan last week. R22 went in vertically after apparent loss of power for reasons yet unknown. Witnesses reported he was hovering OGE at several hundred feet of altitiude. (Yes, he was operating in a dangerous part of the performance envelope, but he couldn't do what he was doing -- comb through a wooded area for a fleeing convict -- any other way, really). Of course, a chute isn't going to be much help on a fixed-pitch helicopter like the original subject of the thread. A gyro is always in autorotation, a helicopter has that option in most of its performance envelope, including the part where you always fly unless you can't avoid it. With a fixed-pitch helicopter, you are betting your life, or serious and painful injury, on the reliability of that motor. cheers -=K=- Rule #1: Don't hit anything big. |

Ballistic Chutes on rotorcraft, was I Want One - I Want One - I Want One
Hi Kevin,
Thanks for the response. I hadn't heard bout the two stage deployment you mention. Seems to me you've have to have plenty of altitude to have time for everything to stabilize inverted, then deploy the second stage to right the machine before landing. I'm not sure I'd want to go through the flip that would occur at that point! :-o Besides, it seems to me that gyros as a rule, don't fly high enough to take advantage of that? Of course, all it has to do is save one life to be worth it I suppose. At least no one's been forced to find out whether or not this will work for real, so far! :-) Fly Safe, Steve R.
