Would like a straight forward answer by someone who knows. Please.
So, let's say you build a custom landing gear. The wheels bounce BIG TIME on landings. Not even a real airplane would bounce so much on the worst landing ever.
I think it can be compensated by weaker shocks but, can you change some of those XML settings to cause it to not bounce so badly.
@MAINE the design matters quite a bit. seen plenty of builds but i can tell some geometric setup works better than the others. personally i like the av-8 harrier type. i like it quite a bit more than most of the newer american carrier jets. if u want something that works right out of the box u can try this excellent front gear from bogdanx, on his meteor
@47parzival41 No, I flew in other aircraft. I would see the U2 takeoff and land daily.
@ChiChiWerx I hear ya. Of course aircraft dependent as you know determines the stall speed and approximately where you want to be on touchdown. Actually had an aircraft where the wings were re-installed and the stall point was marked as 120Kts but it would stall every time around 125Kts. Gauges were checked, doubled checked, swapped and it ended up being the wings were off by a fraction.
As for the U2 I had the pleasure to watch it's near vertical takeoff and having mt ear drums ripped out nearly every early morning around 4am during our liberation of Kosovo. I was in the Navy. (so not our aircraft ;) ) I had to sit and wait for our planes to land to refuel and load ordnance.
@ChiChiWerx Oh ok, this is helpfull :)
@TrislandianAlliance, landing on speed should be accomplished on every type of landing, whether it’s in the boat or on a runway. On the boat, an on speed landing helps ensure you a. Don’t fall out of the sky prior to hitting the deck, b. That the hook engages a cable and c. The plane doesn’t break the wire on engagement. On land, landing on speed helps to ensure you a. Don’t fall out of the sky prior to hitting the ground, b. Land in the first 1/3 (or less) of the runway and c. Validates your landing data so that you don’t go rolling off the end of the runway while standing in the brakes. Every plane I’ve had the pleasure of flying has also had published evaluation standards which make sure pilots fly on speed on final—the U-2 has a 2 knot window of -0 to 2 knots fast for a no flap approach, the T-38 was something like -5 to 10 knots for a normal landing and the mighty Guppy stabilized approach criteria is only “momentary” deviations of -0 to 10 KIAS below 1000’ AFE. Seems tight, but when you use Autobrakes MAX on a 7,000 ft runway in gusty winds and your stopping distance is more than 6,500 ft, you’d best land on speed in the touchdown zone, otherwise you’re going to surprise all the pax in the back of the jet when you have to go around or while 4 wheeling off the end of the runway. So, yeah, regardless of the runway, land on speed.
@ChiChiWerx
land on speed
, seems like something that you would do at a carrier landing@Viper3000ad HA! If I ever bounced that much on a real landing I would have poop in my pants. Bouncing like this is assured crash/death in a real world situation.
Try to land smooth. Hold the plane above the runway and bleed off all the lift before touching down. If it helps, then change the shock's damper and spring to 250%. If it still doesn't help, then add more wheels. That should share the load even more
Go around and come back in a new approach! :-)
try add more mass to the wheels.
Damper on the shocks of your custom gear and lots of it, whatever it takes 200%, 300% or 1700%. This reduces your landing gear’s “springiness” and resultant gear rebound. @brians1209 that’s not a solution that’s practical for every build. Many builds don’t have drag chutes, pilot technique varies greatly (especially here) and simply not landing fast doesn’t necessarily reduce bounce, and not even a hard touchdown guarantees a bounce. However, even for experienced pilots, the gear has to provide a moderate degree of shock absorption (or more, if landing on the boat), which requires higher damper values. Considering these factors and reading your advice, I would like to suggest you reassess your “very slow” landing speed and change your advice to “try and land ON speed”. If you’re consistently bouncing, you’re right, you’re probably landing fast.
Damper
My plane bounces too. (Custom landing gear)
I just hit the drag chute immediately when my gears touch the ground or either land at a very low speed. Maybe it bounces because you landed at high speed or your plane has too much lift.
@asteroidbook345 You can never have too much cow bell lol
Maybe make it more rigid.
