So that's cool.

Someone in the comments to the YouTube video noticed loss of aileron:

If you pause the film at 42 seconds you can see the aileron leaving the right wing. Which would explain why he couldn't roll right to maintain level flight. Having broken ailerons would cause very abrupt control inputs at race speeds. I've screenshotted the video play by play and from 41 to 42 seconds you can see the aileron disintegrating and leaving the air craft.

Here's Juan's take

I wondered about this initially as it looked like he could not roll right.. but the l29 has stout pushrod control actuation, so, even if he lost an aileron the lift generated by the left wing and a downward deflected left aileron would have rolled the plane upright....

Still the simplest answer is usually the correct one... G induced loss of consciousness.

In jets, at those speeds, one would not use the aileron to roll because at such speeds typically induces adverse yaw.. Rudder is typically used instead

I say he blacked out, never knew what hit him


What I don't get is how people with sooo much to loose, take such humongeous risks..
Everybody now says things about loss to the family, but those who do such things willingly take those risks, if anything they know its a bloodsport.
So they choose it over their family.
Same with climbing the Everest, and those who want to do it without extra O2: you know its a high risk of dying at those altitudes
You choose it over your family.


To some extent i can understand it from young men in their prime, who haven't hitched or got kids yet.. but 60 year olds.. grand fathers higher risk and much more to loose.

damn..
2 things I wonder

1
Israeli F16's , I would expect those airframes have been used to within an inch of their life before they give em up.

I wonder how a contractor for profit, will deal with airframe rebuilding and checks to keep em up to spec for ACM, I mean the cost involved is not a good thing in a for profit. Will they cut corners?

2
How far did they have to demil those F16's to be allowed in private use
Even if its as contractors, I would expect the M16 vulcan to have been removed. ECM bits, Link16(?)

But they still would need the radar, UHF radios and Sidewinder seekers for intercepts and ACM?

Loosing the Vulcan and some other stuff could actually bring the F16 more in line with the abilities of the YF16, smaller, lighter, more agile then a regular "fat" multirole 16
Totally slick, and on a diet... It would have better acceleration and better turn rates then a regular F16?

Its written in many books that by topgun CO and others that they stomp the rudder if they quickly need to roll out of something. Like Guns Defence.
Because it is faster to roll and does not cause adverse yaw, somethign that has been causing trouble to pilots since the F100

Rudders to roll, aileron to compensate for the yaw.

I'm not making it up you know

And for our helicopter brethren, same kinda dealio. Different platform but still dangerous AF![emoji51]

I kinda wonder how reliable lasers work when there is heavy rain/spray?

It may be, but I would be shocked if it is anywhere close to 495000 pounds for cost. That would be a serious disruptor in the private helo market, that just barely buys you an Enstrom or an R22 which is, by all appearances, a lot less machine.

gwood 09-21-2022 10:16 AM

It's a kit. You have to build it.

svandamme 09-21-2022 10:34 AM

Do people with 495K spare change actually have time and interest in building a kit helicopter??
Seems like an odd combination?
