I guess modern modelling software is capable of simulating that, but overdesign as a precaution?

that was my point exactly. I think it is only possible at the large budget OEM. With large scale test jigs running for years. The H160 is an example of that.

Must be difficult to find 10 avalable such professional engineers because it seems that there all very busy here on this topic ... :E

Literally every brand new car that has ever been developed. You know when you go to an auto show and you see upcoming models on spinners and nobody is allowed to approach it or open it? Those are non-working pre-production prototypes.

Pull the other one. Too much cool aid can lead to all sorts of cognitive dissonance.

It still makes us ponder that so many of the posts on this thread are based on “the past experiences in the aerospace industry”

As the first media outlet to publish an interview with DrJH in Nov20, it’s been clear from the start that he’s taking a different approach to everything, and (intentionally) employing experts from motorsport and various other industries away from flying machines. While that makes for “interesting challenges“ along the way, it also means that you need to understand the other industries to make valid comments.

The human race does not progress without pioneers, and the UK has seen more aviation pioneers than most countries - our office is based on the airfield where Hawker, Sopwith, Bleriot, AVRoe and others built and adapted the early flying machines 110+ years ago,

Assuming it all comes good (we remain optimistic), we look forward to celebrating another British aviation pioneer. As we read this elongating thread, we smile at the increasing number of naysayers who will have to publicly eat their hat/underwear/etc just to keep face when the HX50 takes to the air.

if we’re wrong, we’re fine with that. But we think the industry needs something like HH to jog itself off the assumption that you can get away with charging ridiculous prices for spares, etc. (Just look for Dick Smith’s posts on A109 avionics as a start)

Nope. I don't think anyone here said it will not take it to the air. We just said it can't be done in timeframe and for the price and giving us quoted performance.
So far, timeline is busted. Other parameters remain to be seen.
Why is it that Hill supporters keep forgeting that?

Yes, and how would one got about repairing such cracks and how long would those "bandages" last, how effective would they be.Only years of testing would be sufficient to determine such a thing, and only time will tell if the next elon musk has everything figured out as much as his customers hope he does.

completely agree Shagpile. It’s getting tiring. This forum has become about a bunch of grumpy old knockers, not helicopter enthusiasts. Rather than great dialogue about a new helicopter being developed, it’s all just pessimistic knocking on every possible front. Timelines, cost, carbon fibre, engines, etc and I’ve come to realise the handful of guys that dominate this forum have such an entrenched negative view and will never be open to embracing anything new. I’ve had enough of this “forum”. All the best to everyone.

Or, in fact, a number of very experienced aviators with many thousands of hours and collectively hundreds of years flying and operating helicopters.

Yet inexperienced PPLHs are happy to take a salesman's optimistic view over a huge wealth of knowledge and experience - certainly far exceeding Dr Hill's.

If the grumpy old men are pessimistic, does that not ring any alarm bells amongst the faithful or are you too in awe of the new kid on the block claiming to have all the answers?

He's not the Messiah, he's a very naughty boy:E

I just wish CRAN would post here and and contribute to the discussion...

I have not been watching this thread much as the discussion seemed to diverge from what it should have focused upon......that being the development program of what might be a very innovative helicopter design.

For the young Pups that are taking exception to some critical views about the design and such.....remember those old dinosaurs got "old" in a business that is not very forgiving of those that are not on top of their game.

When the old guys raise good valid questions it might behove you to slow down and consider what they are questioning.

Personally, I give a hoot about the Hill thing.....but that comes from the luxury of being retired and having more important things to fret over.

I bet a lot of folks thought Frank Robinson was doomed to fail when he set out to build his helicopter....but we see how that turned out.

Everyone has the right to try. Interesting to note that Hill has nearly 2X orders than Robinson had when R22 got cert. If nothing else, shows that market is ready for something other than "same old."

see this is exactly what we are talking about Crab- spouting off ill informed comments- you claim the wise old pessimists on this forum have a quote “huge wealth of knowledge and experience” yet you actually have absolutely no idea about the flying credentials of the other knockers on this forum, who anonymously represent themselves by pseudonyms, For all we know some of them may not even be helicopter pilots,

And you refer to us HX50 deposit holders as naive inexperienced PPLHs yet again you have zero facts to base that on. Using my example to merely illustrate this point, I have been an aviator for 25 years and fly all sorts of aircraft, hold a CPLH with night rating, low level rating, sling and mustering endorsements, and an instructor rating, and have 1000hrs of rotary time in command. And I know for a fact that some of the other people who have put deposits down are vastly experienced helicopter pilots as well as highly intelligent, successful people. So wake up to yourself and stop assuming we’re all idiots.

Out of interest PP, you might like to know that in the military, 1000 hour pilots were considered the most dangerous and most likely to have a crash because they thought they knew it all.

You don't know how many of us here know the experience levels of others from other threads and off-line chats.

I could bore you with a list of my experience and qualifications but most of them (other than being an ATPLH holder since 1991 and flying since 1982) won't mean much to you.

Steady
 

Whoa Whoa kids, calm down.
Let's not take this thread to a personal level.

Shall we just say that those who want to believe are doing so based on optimism, charm and the desire to see someone succeed. No problems with that.
Those that don't want to believe do so based on experience and pessimism.
There are highly intelligent people in both camps, however only one camp will have depositers.

Good luck all involved.

You're right Jeepys but can you spot which antagonist started the downward trend?

[[email protected];11511177][1000 hour pilots were considered the most dangerous and most likely to have a crash because they thought they knew it all./QUOTE]

yep agree with that.
And also agree that I don’t really know that much-
Indeed the more experience I get the more I realise just how much I don’t know.
Was just purely illustrating that some of us gullible muppets who have put deposits down are not just simple PPLH as you have stated. That’s all.

Clearly you have vast experience Crab. Congratulations. Regardless of the difference in philosophy and opinion here, of course there’s inter-pilot respect for anyone with that sort of aviation experience.

That's not a difference in philosophy - that's just being rude.

​​​​​​​i have no problem with being disagreed with, it's just the manner that is too symptomatic of modern internet attitudes.
