Fred0311 Posted August 1, 2016 Posted August 1, 2016 Are those people also pilots who understand the danger in what they're doing? 2 Quote
Wally Posted August 1, 2016 Posted August 1, 2016 I wasn't born yesterday. How heavy, how high? What's a good book prediction for comparison?Four small skinny guys in jackets (cold, maybe?) and 22 minutes of fuel is one thing, and I can replicate that... 1 Quote

Hi Wally , The TTOW was 1750 lbs. including fuel , the crews weight,skinny ore not is 700 lbs. the elevation was 2500 ft. With what 2 seater helicopter would you like to compare it with ? Have I missed any modern piston engine helicopter regarding performance on my spread sheet ? 1 Quote

avbug Posted August 6, 2016 Posted August 6, 2016 Those "informed pilots" look like two kids hanging on to the side of the helicopter with no harness, their hand a few inches from the mast and a foot beneath the rotor, to prove what? If you're doing a performance test, why wouldn't you use ballast such as water or other disposable load? Four people in a two-seat helicopter for what purpose, exactly? The first thing that came to mind was that this is a demonstration of stupidity. 3 Quote

Hi AvbugIt is a no brainer to make that test with water ballast first, (total crew weight 700 lbs.) the only problem is nobody would belief it or watch such a video.The video clearly demonstrate only, the safety margin built in to the 2 seat helicopter.Did you actually study my attached performance spread sheet?I know it is hard to believe my turbo Rotorway is on top of all piston engine helicopters regarding hover performance. All verified on my previous videos.Common guys we are all pilots and love our machines , there is no need to criticise somebody’s success . Quote

OP/Sir: So you want people to notice that you have achieved performance and at the same time have experienced professionals disregard standard industry practices for determining performance, weight and balance, ballast operations? Do you verify what the max designed skid loading was? As a member of the US Helicopter Safety Team, many of my peers have discussed these kinds of videos and the example and mind set it shows. My USHST peers have written a Safety Bulletin about showing the correct example. http://ihst.org/portals/54/training_videos/Setting_the_Right_Example/story.html http://www.ihst.org/portals/54/IHST_News/2014%20Right%20Example%20Bulletin.pdf So, you were successful in showing a disregard for industry standards and risk management practices. If you want recognition and accolades you could do better. Mike Edited August 6, 2016 by Mikemv Quote

Your concern then, wasn't safety, wasn't research, wasn't aeronautical science, but being seen; you put lives in danger and acted stupidly so that people would be impressed. That makes your act all the more pointless. Putting four people in a two seat helicopter isn't success. It's stupidity and bad judgement. What is the point of exceeding aircraft limitations or established parameters in the first place? 1 Quote
arthur gemperle Posted August 7, 2016 Author Posted August 7, 2016 Thanks for all the comments , I do understand and will follow the code of conduct for helicopter pilots. Quote
whoknows idont Posted August 12, 2016 Posted August 12, 2016 I understand the benefit of a turbo charger to achieve sea level power at altitude. But is this really sea level performance? Even with minimal amount of fuel you must have still overloaded the A/C by around 200lbs...How do you make sure you are not over-torqueing the living crap out of it? 1 Quote

Even with minimal amount of fuel you must have still overloaded the A/C by around 200lbs... How do you make sure you are not over-torqueing the living crap out of it? Hi , sorry I don’t know your name , but I am glad to answer your question. Rotorway manufacturer specification, is at sea level maximum boost 34 inch. on their supercharged version ,which is a very low boost , that produces the maximum torque . So at sea level, with standard pressure and temperature, theoretically any Rotorway could lift that weight with maximum allowed boost and power . The helicopter is designed for that torque as Rotorway once wanted to built a 4 seat helicopter . Rotorway has de- rated the max. take off weight to have some safety margin left in flight and for higher altitude . Now with my own designed turbo altitude compensation system , using the same maximum 34 inch boost or torque , I wanted to demonstrate that safety margin is also available at much higher altitude with my turbo system, as proven in all my previous videos . Rotorway has announced to bring out their own turbo system , most probably inspired by my success .They have discontinued the supercharged version . I hope you are satisfied with my answer . I do admit my water ballast test should have been good enough for me to prove it , but would you have believed it ? Regards Arthur 1 Quote

Regards Arthur I wouldn't have cared, so belief or disbelief would be irrelevant, but you'd at least have operated under the guise of an intelligent, safe scientific approach to your efforts. In this case, you put lives at risk, operated in an unprofessional and unsafe manner, and made your work more of a spectacle than a credible effort, all for a photo opportunity. Perhaps it's true that a smoking hole in the ground is a small price to pay for a cool picture. 1 Quote

Just like we have to take your word that you didn't exceed the 34" and that this is really at 2500'.The whole point of trying to prove something by making a youtube video is a lost cause if you ask me. If you were just fishing for compliments you couldn't have come to a worse place for that.I'm not trying to belittle your achievement, don't loose your enthusiasm!A couple of good pictures of how you did it would be a lot more interesting than that video.

r22butters Posted August 13, 2016 Posted August 13, 2016 How dare you invent something then test it by putting poor naive pilots on the skids, that is so unprofessional and reckles! ,...now if you'll excuse me I have to go scud-running for the all mighty dollar. Quote
Spike Posted August 13, 2016 Posted August 13, 2016 Back In 2005, then Eurocopter test pilot Didier Delsalle landed an AS350 on top of Mt. Everest. Since that time, no AS350 has landed there again…. So what was the point? The helicopter can go where no one can take it? To land on Everest just because it was there? A dangerous way to prove a meaningless point. Yes, I understand it was a Marketing gimmick to sell helicopters, but, don’t you want to sell helicopters to people who are intelligent enough to understand the specifications of the machine without all the drama? And, BTW, the 350 I fly, can’t even meet those spec's so again, what was the point? In this case, while the product is innovative, technical information should’ve enough to generate interest in the invention. However, I’d suggest to those who need to increase the power of their Rotorway in order to carry 4 people, to simply purchase a more powerful 4 place helicopter…. Quote
r22butters Posted August 13, 2016 Posted August 13, 2016 ,...and that's why we haven't been back to the Moon since the 70's Quote
AS350 pilot Posted August 13, 2016 Posted August 13, 2016 I think for the first time I have to disagree with Spike (partially). Landing on Everest with the Astar was proving to the highest degree that they are far and away the best at building the high altitude leader in the helicopter business. 10 years later Bell is bragging about landing a 407 at base camp some 20k'......so I have to say I think it proves a very relevant point by landing there. Additionally, putting 2 folks on the skids of your rotorway and probing it can HIGE at 2500' or whatever is entirely different and honestly really stupid. And as Forest Gump said "that's all I have to say about that" Quote
