Max speed for landing smoothly.

[GuntiNDDS]

anyone got some figures, whats the max speed is you should have when engaging landing (from about 5 meters or so), to be able to land smooth ?

 

thanks.

What do you mean by 'Engaging' landing?

 

Personally I always land from a Hover - as a consequence Airspeed is at Zero or as close as.........as for descent rate, I like to keep it at about a meter/sec or less for the last 5-odd meters or thereabouts.

 

Feather the collective and you'll be putting her down as light as a feather/smooth as silk :)

I've made rolling landings at up to 50 if I remember correctly. But be carefull not to blow the front tire.

[Frederf]

I wouldn't be afraid of doing a rolling landing on a hard runway at 90 kmph or so. Usually there's no need for these speeds though.

[AlphaOneSix]

By the book, your speed during a running landing should be between 30 and 40 km/hr.

I've landed doing 150-180 before, but my tires didn't survive... Other than that everything was in good shape.

[CAT_101st]

Same as Mack but with out the tire isue. :D

[Shrubbo]

300+ is do-able with no damage if you know what you are doing :D

[159th_Viper]

I see this is turning into a P~#*ing Contest........:music_whistling:

 

:D :D

 

'Fess Up - Who's the Hotshot barrelling in at 320+ and leaving donuts on the active?

[AlphaOneSix]

If you knew what you were doing, you would be landing at 30-40 km/hr, not 300+. ;)

Who thinks here his BlackShark fly (& land) like a TigerShark :megalol:

 

Very Fishy :smartass:

 

 

If U R quite good then U can land on the top of the control tower of the Kuzi. With zero speed with your verticopter :)

lol.

 

thanks for your numbers. so between 30 and 300. rofl.

 

i been practicing landing today, and i dont come with zero forward speed yet. i been doing landings between 10 to 4 forward speed, and didnt have any tire issues or something. just when the front wheel touches the ground, there is a little shaking. i would like to minimize that a bit.

I didnt read the book :book:

haha :D

[glottis]

Only chumps land at airports anyway, a real KA-50 pilot would always land on a moving train.

The point of landing fast on a runway is that a slower landing is not possible due to lift issues. On a really hot day at a high altitude the aircraft would not safely be able to hover-land.

 

Considering the maximum lift is achieved at 130 kmph that would be the fastest one would ever want to go to land but situations that require a fast landing are few and far between, perhaps an engine failure or other mechanical problem.

 

I mean I guess going faster you could pull up and flare to land but that's not sustainable and pretty wreckless.

[AlphaOneSix]

During an autorotational descent, the recommended airspeed is 120-140 km/hr (130 is ideal). Of course, you don't land at that speed. If you landed at that speed, even though it is your best speed for the slowest descent, your aircraft will hit the ground too hard and crash. This is the whole purpose of the flare, to trade off that airspeed to further decrease your rate of descent. On an unimproved surface where you can't really roll well, the ideal is to flare and reduce airspeed to nearly zero for touchdown. On an improved surface, the ideal landing speed is the same as for a normal running landing, 30-40 km/hr.

 

The 30-40 number is because the ideal landing speed during a running landing for a helicopter (any helicopter) is right around the speed where it enters translational lift. For the Ka-50, this is 33 km/hr.

[Frederf]

Indeed 130 kmph is the best speed for lift in a continuous, stabilized, long-term flight modes like best rate-of-climb or least rate-of-descent for an auto-rotation approach. I however disagree with the notion that flying a 130 kmph landing necessitates a hard landing. Sure if you flew into the runway like it wasn't there it would be hard but a flare before landing either starting or ending at 130 kmph could be just as smooth.

 

As a student of aviation and physics I must confess up until I just looked it up I had only heard the term 'translational lift.' Certainly being in the translational lift mode (>33 kmph) does improve the landing and takeoff performance (thanks for that heads up by the way) it would not be the litteral limit of performance in landing.

[AlphaOneSix]

My point is that there is just no reason to land that fast, ever. And during an autorotation, landing at 130 will kill you. If someone likes to land fast for fun and games, that's great of course.

[DiabloSP]

I'd like to bring another glass to the table. That 33Km/h speed, is the best for landing even with one engine?

 

I remember being easier to land a bit faster (around 40-50Km/h) when on one engine only, but i'm not really sure that's the way to do it.

 

Thanks in advance.

Well, it's not everyday you can crash and burn a KA-50, in high-definition AND slow-motion :thumbup:

 

That's mostly why I try to do rolling landings on buildings roofs.

Yes, landing speed for running landings is always 30-40 km/hr by the book, for normal landings, autorotations, and single engine landings. For me, I would be closer to 40 than to 30.

Hehehe that is so me :thumbup:

Getting more than 80 kph running you can encounter nose leg shimmy.

Especially if you load it.
