 Posted: Thu Jul 06, 2017 2:53 pm Post subject: Mono Wheel Undercarriage Fairing |
 |
|
Hi All,
I am currently building a Mono Wheel Classic fitted with a Rotax 914 and would like to fit a fairing to the main Wheel. I have read several posts relating to this subject but as yet to see the fairing made by Kim Prout? which I believe is fitted to Bob Jacobsons' and Cliff Shaws' aircraft. If any members have photos of the fairing I would appreciate it if you could post them or email me direct.
My idea so far would be to have a fairing in front of the wheel that covers the hole below he undercarriage leg and part of the wheel when retracted. The rear of the wheel is also easy, as a fairing could be attached to the fuse. The centre part, if it is to cover the wheel, needs some kind of moving cover and this is where it gets tricky. The moving part needs to open and close with some kind of mechanism, preferably by operating the current undercarriage lever, be able to withstand the pressure of the airflow when open and in a yawing manouver, and able to cope with mad splatter and still close when retracted. It could be built as suggested, with 2 to 3 plies of Bid so it would collapse if a gear up landing were made. I am currently modifying the engine cowl ( along the lines of Fred Kliens' idea) and have done away with the current large opening to exit the hot engine airflow. I hope this alteration will allow a main wheel fairing to reduce overall drag without too much of a weight penalty. My gear leg retracts more than most with the proposed second uplock, which will leave the wheel rim level with the fuse bottom.
Any ideas or photos would be appreciated. Thanks.

Ross,
Here are a set of photos of Kim Prout's fairing that we have on our XS mono wheel.

Hi Ross,
I have one that I purchases "way back when" from Kim That I probably will not use. I don't recall how much I paid for it, but you are welcome to it for the cost of postage and packaging.
