^do you guys think Peter knows this?
Good to know, and makes sense to a pilot that has never had the pleasure of flying a canard...yet. I can see if the canard stalls, and my understanding is it should before the wing by design, the nose is going to drop fast and ugly.
I only have one flight in a canard, but the nose didn't drop that fast when the canard stalled. Faster than you'd want a few feet off the ground, but not that fast IMO and certainly not ugly, it's very smooth.
No **** Sherlock.
20mm = 0.79 inches
It is quite likely that the weight of the projectiles follow a cube law, so -
0.30 cubed is 0.027
0.79 cubed is 0.488
So a solid mass would be about 20 times heavier.
However it is a LOT worse than that, the 20mm cannon has room for an explosive charge.
I have no idea how to estimate the difference that might make however I certainly would not like to be on the wrong end of it.
Depends on the plane and weight. And it's hard to appreciate at 1,000' AGL. When the nose comes down, the plane accelerates... down.
In my plane with just me in the front seat, I don't get a pitch buck at all. Just a 400fpm level descent. Put another person in the front seat full fuel and the nose drops noticeably. Add some baggage and while it's not a violent drop, there's some mass and inertia behind it. If that happens 3 or 4' above the runway, I'd give even money on collapsing the nose gear.
But that's my plane. A four place plane with an empty weight under 2,000lbs. Probably not nearly the same outcome as a Long-EZ. But much worse in this pig of plane that's empty at what: 3,200lbs?
Worst landing I’ve ever done was in my Velocity. Very gusty day with another guy up front. Just lost all lift at 3-4 ft above the runway. Like an F-18 slamming aboard a carrier. Hit so hard it popped the nose tire. No issues with prop clearance though.
I cringe every time I see German gun camera film of a B-17 taking 20mm cannon fire. There are pieces of the aircraft flying off, and there's no doubt the tail gunner is dead. Ugly stuff.
Off topic but just watched The Cold Blue today. Excellent documentary.
Looks like there are some issues.... throttle communication to the ECU seems to be cutting out and the elevator trim moving to a nose down setting as airspeed increases.
The total of this absolutely shocked me.
My Bellanca Super Viking does. Three small static ports just behind the raised ring area. Plus another port at the rear of the assembly.
Something something a fool and his money?
After watching the latest video, I'm guessing by Sunday the aircraft will be in the weeds. His hand was shaking as he reached up to flip overhead switches.
After misplacing a data entry decimal point on the throttle range when the aircraft was reassembled, the engine went to idle during one of PM's runs.
Then he discovered the canard elevator is flattening out and losing positive pitch as the airspeed increases. Solution: Crank in more positive trim. No need to change the trim spring. This means as the canard AOA changes at liftoff, the elevator pitch will also change. How much? Who knows?
Thought he had a new local test pilot? Well, at least he has a flight suit now....
Reminds me of "The Defender". I thought it was a spoof along the lines of "This is Spinal Tap", but I'm not sure - this guy might be serious. The result is the same though - it will never fly, just like the Raptor.
This is a well known... feature with canard elevators. The low pressure on top of the canard sucks up the elevator the faster you go. Velocity's have a "sparrow strainer" (a small upside down wing) on the trailing edge of the elevator to counteract this and relieve the force on the trim spring. Some builders never install them of remove them. If your trim spring is strong enough, it's no problem. But if the trim spring breaks (or breaks loose), you could wear your arm out by the time you get back on the ground.
Oh ffs. It just keeps getting worse. His family will miss him. So very selfish...
Movie theaters are charging almost $20 for an adult ticket. Buy one for your date, a large popcorn, a couple boxes of candy, and a couple large sodas and you're in it for $100. At the end, you'll probably walk out disappointed because most movies just aren't that good. Plus, in 2020, you'll come home with the rona.
The guys kicking in $1,000 confuse me a little, but I can't say anything bad about a person who decides that he is more entertained spending $20 to ensure another Raptor prototype video than on Star Wars 10: The Tears of a Generation.
Seems more like spending money on snuff films than Star Wars.
'The Tears of a Generation' lol.. sad but true. Disney is awful. Kathleen Kennedy is on her way out. Rumor is Mandalorian's Favreau will take a bigger role in Lucasfilm
I can see someone donating $20. That's little more than a movie ticket before Covid. Heck, everyone here has had 22 pages and 862 posts worth of entertainment.
$20 just keeps the show going.
I'm telling you.....put Christopher Nolan on the next 3 Star Wars films. They will be epic. But nobody listens to me....
..in the meantime, this other unusual plane is successfully flying: https://www.pilotsofamerica.com/community/threads/the-otto-aviation-celera-500l.119285/page-2
so lets see, the throttle is working fine for a bunch of runs, then fails to idle and the solution is just re-calibrate it? the engineer in me says, "interesting, why did it loose calibration? a fly by wire throttle system has to be foolproof, even better, foolproof with with a backup. the sad part is with decision making like that the go fund me page may be a go fund me to pay for his funeral expenses.
I wonder if Jerry would be willing to test pilot for Raptor.
Don't worry guys, he slapped some tape near the static port. Should be all good now -- Oh wait, it didn't accomplish anything. Damn, guess he'll try again later.
I was like 13 when I saw Spinal tap. I truly thought it was a real band. The line of "don't touch it...it can't be played" kind of reminds me of this err...plane?
Wasabi indicated his pitot has a built in static port. I just don’t get why he doesn’t hook into that.... seems like the dicking around with the port he’s got is wasting more time.
Peter has a lot of bigger issues to solve.
Static position and/or configuration can be determined by trial and error. It is a bit of a black art. No ASI is accurate through the entire speed range, but as long as it is consistent at a given point, you can use it as a reference, because that's what you need it for anyway.
The addition of a flight suit concerns me that he is going to try to fly the thing himself. The incredible self-righteousness he has displayed makes me fear that once he’s run out of possible test pilots, he’ll decide that he needs to do it, rather than stopping to ask himself why he ran out...
Yup. We all know he's going to. He's just talking himself into doing it. Every video I post a comment urging him to reconsider. Here's what some of his cult followers posted in response: I hope they feel responsible for his demise when he ends up crashing.
Truly inane stuff.
Because the wright brothers were taking off in a 3000 lb machine at 100kts right?
One would be amazing, one would be garbage, and one would be unintelligible but have a cult following.
And it goes to eleven! LOL
He thinks he can "slowly" open the envelope himself. 8000 feet of runway disappears fast at 100kts when you are in ground effect or not.
Peter doesn't need an accurate altimeter or ASI, only a dumb liberal commenter on Youtube would want that. You think the wright brothers had that? All he's gonna do is fly it into ground effect. It will literally go perfectly, nothing can go wrong. Then he'll fly a loop around the pattern all by himself, because who needs experienced test pilots. That's for *******.
Just remember folks, you ain't cool without walking away from the explosion.
I hope it all goes well for him. I would never want to see someone spend that much of their life on something and not succeed. Didn't someone build a twin Vans RV and crash it on the maiden flight?
He's going to taxi that plane to death. At least I hope he does, so he can't try to fly it.
On the bright side, the NTSB will have plenty of data points for their investigation with all the cameras he's using.
