Propeller Build Gallery

The construction of the tip rocket propeller is shown, step by step. Click on the thumb nails to get the full size picture.

Starting material was a GlueLam wood sheet

The profile was carved out with a hand held electric miller

Than I used a hand held electric planer and finally I sanded the blades

Installing the Tip Rockets

Fixing of the rockets with screws into the wood.

Epoxi Putty of the rocket pipes

Silicate putty with high heat resistance and good heat insulation.

Putty and fixing of the straps to get them parallell, horizontal and centered around the center of gravity line (located at 25% of the chord width)

Mounted Straps

Mounting of the hub bar. The 2 degree pitch angle is made with aluminium plate shims.

The shaft bolt has a hole drilled thru it and threadings for the hydrogen peroxide swivel connectors on both ends. On the picture is only one bearing. In the final version I installed double bearings.

The propeller tip rocket system is ready and assambled.
