I'm brand new here. So maybe I am asking a very stupid question:

if I install the engine vertically, that is flywheel down, what will happen? Certainly the oil pump intake in the oil pan should be relocate to the flywheel side and oil level sensor also is a problem, is there any suggestion for such installation mod? And the most difficult part is during the operation, the engine will turn to stand up position again. In other words, I need the engine operate at both vertical and normal position.

I saw a guy install Renesis side-up, which is made the oil pan at side, and he has no mod and claims everything is normal where oil level almost same. But ends up would be a total different story. The thing is I won't put it long at vertical position ( about 5-10 min at max), problem is need run at max rpm even at red range and you know what I apply for

 

 

Maybe the OP didn't notice this was a car forum not a helicopter forum.

Good luck

 

you building a renny powered push lawn mower on some kind of aircraft?

 

There are people that install rotaries in planes using a method that is called "plugs up" where the engine is installed with the engine rotated 90 degrees so the spark plugs are now on top of the engine. What this does is to allow the intake and exhaust to both be on (new) bottom of the engine which makes packaging them easier under a crowded cowling. The oil pan doesn't work sideways though so a plate is used to block off this side of the engine and a new sump and pump are used under the engine installation.

Something similar to this sump is going to be needed if a rotary is to be operated flywheel side down. The pan will have to be blocked off with ports that allow oil to drain to a new sump with a new oil pump. As long as the engine can get fed with oil and fuel it doesn't really matter which way it is pointed.

What application is this going to be used for?

 

now i want to build a rotary push mower damn it. ive seen the racing lawn tractor with a wankel. it would be a bitch to push but grass wouldnt stand a chance. lol

 

You would have to be careful what direction the blade was facing. At redline it would turn into a hovercraft.

 

Thanks for the idea. Seemed some mod can be done for the purpose.

id hate to lose compression while flying a rotary powered aircraft.

 

I know it sounds funny. But thinking about there are only dozens use Mazda rotary for flight, and even fewer for renesis, comparing thousands here who know this engine from inside out, so just an out-of-box idea might get more resourseful inputs from here then there. I believe "MOD" is the spirit of the forum, certainly this one is extraordinary than most. Most people laughed at Wrigt Brothers with their funny bird, but without them, where are we now? walking monkey?

 

<-- Mind Blown

 

Unlike piston engines, rotary engines rarely have catastrophic failure. They get weaker over time. Even if you did lose one rotor, you still have the other one that will allow you to control a forced landing. If you loose a piston, you will soon loose the whole engine.
