Using this video to teach my kid, whose taking AP physics, that vectors, acceleration due to gravity, f=ma, and various other basic physics calculations are actually used in the real world. Airplanes are truly awesome. Can’t wait to order my RV14 kit and have her help me build it.
Still hopefull to build a 14, 26 yeatr A&P here with 3 boys that love aviation. 2 are current new A&Ps with the third 15 year old wanting to fly commercially . I see a Plane or two in our future :) Keep moving forward !
Thought my friends would like to see how Vans (the manufacturer of the RV14 kit) has tested the RV14 airframe I am building. It makes me even more confident in the kit I have chosen. This is a tremendously strong airframe. Everything I have built to date has assembled perfectly....absolutely. It is an amazing kit, so precise, incredibly strong, a tremendous confidence building project. You almost have to see it to believe it.
@@Kevin---kx3jy I am close. Currently all airframe components are complete. I am installing the wiring harness for the avionics. All the avionics are in place…I’m just running the harness and securing it. Next step is to move everything to the hangar and bolt on the wings and tail and hook every thing up, get weight and balances and a 1st engine start prior to inspection.
@@davidhays5020 congratulations! A friend and I are building a 14A in Santa Maria, CA. Airframe is done, panel is done, engine got hung last month, and the prop is going on this weekend. We will be moving the fuselage to the hangar soon where we will install the wings and do all the fiberglass work. It’s getting exciting. Where are you located?
"If you landed that hard, you might owe yourself some new wheel pants - and probably some new underpants as well." BWAHAHA. Awesome. Typical Vans humor.
isn't the drop height was too low? i mean the velocity at which it touches the floor was just like as if we're jumping off a dinner table? does it reflect real situation?
Yes it does reflect a real situation. Keep in mind that the landing gear on an airplane is never designed to absorb the loads induced with a drop from any height above a runway (there is a point that an arival would be considered a crash). As described in the video, when a wing stalls, the amount of lift it is producing does not go to zero. It just has a sudden reduction. So if we are wanting to simulate a drop from 3 feet because of an inadvertent stall, we wouldn't drop the test airplane from 3 feet high, because there is no way so simulate the lift still being produced by a stalled wing. So engineering calculations are made and the drop height is adjusted to produce the known amount of decent rate that would exist at touchdown.
Basically, engineering can't save you from pointing the nose at the ground and applying full power, but it's intended to provide the most protection it can for a reasonable situation that might get out of hand. Interesting video!
that frotn wheel is a terrible design, if the plane is carrying too much weight, lands too fast, or nose first. the metal will touch the ground first and sending the wheel shaft straight to the engine.

Don't know much about plane engineering, however I'd trust this landing gear to all others I have seen...

I trust this design 10 times more than any other ones.

Did you complete your project and get it flying?

The RV-As don't seem to have a problem landing except when the nose wheel falls off and then the nose gear sticks into the dirt.
Impressive. Do you guys use strain gages to verify stresses in critical areas?
is there any standart have ?for this experiments and about desing ? EU - ASME-or another ?
Fantástic 👍

Interesting video!
These test are done to standard and not a gram above or an angle steeper. Remember these aren't sold to the Navy

Why are the wing's breaking off? I just read another report on flying magazine.
That is a lot of flexing. Now add two wings, two people, luggage, fuel, canopy, instruments, etc and lets see if they yield!
weights are added inside the plane for this test.
Yes. As mentioned, the inside of the fuselage was ballasted to simulate what the actual weight of a flying airplane would be.
We can do without the music
