Actually these types of engines are popular for the home builder entry level airplane/gliders.

QUOTE(Nacho @ Aug 24 2020, 02:52 PM)  Actually these types of engines are popular for the home builder entry level airplane/gliders. -Nacho With the way the prop is attached, I wouldn't even taxi down the runway with that engine. The thrust bearings in a VW motor are not designed with a propeller in mind. Remember, you are pulling all of the thrust created by the propeller against a magnesium engine case. Most home builders use a reduction unit of some kind, both to absorb the thrust load of the propeller and to lower the propeller speed to something that won't have the prop close to supersonic. 3K is about max speed for most fixed pitch propellers. Looking at that picture, I guestimate the prop to have a 30 inch radius. So doing the math, the prop tips are moving at 536 mph at 3000 RPM. AT 5500 RPM (about redline in a VW pushrod engine), the prop tips would be at 767 mph, or Mach 1.2. It definitely needs a reduction drive to use it in an airplane. Clay |
