Thrust Vectoring Autonomous LEM (Lunar Excursion Module) Build

New Project. Decided to use my thrust Vectoring experience to build this awesome machine in honor of 50th anniversary of the moon landing.

Using foamboard and a laser cutter to build the body. I haven't completed the 2D plans yet as this is a complex structure to create with fomboard. Trying to stick to the original design as much as I can but need to do some tweaks due to the requirements of the EDF and the thrust vectoring system to work at peak performance.

Unit will be autonomous and will possibly be released from a rocket for an autonomous landing at the home coordinates (Will think about that later, as the unit needs to fly first).

Below are some pics of the design and a footage from the cutting of the first body part. Will try to post as frequently as I can.

First stage of the build is complete. Now I have a base structure to build around...

Thrust vectoring nozzle in action. First time working with this nozzle. We'll see if it'll do the job.

Indoors tuning test. Not an easy one. So far tried all my tricks but couldn’t fully overcome the wobble. Not a good sign but will keep on trying some different setups.

Re: Thrust Vectoring Autonomous LEM (Lunar Excursion Module) Build

Well, I wouldn't say it's too bad at the moment for something that by design is inherently unstable. I can't tell from the previous video, but is it just a nozzle or are there some internal vanes to help with the direction of the air flow?

There are internal vanes for yaw stabilization.

Try adding landing gear some weight below cg will help stabilization , love it,!!

This is awesome!

Do you have a gyro on it at all?

Re: Thrust Vectoring Autonomous LEM (Lunar Excursion Module) Build

As the 50th anniversary comes up in a few weeks this would be quite the feat. Good job.

I'm sure we all have our "Remember When" stories there.

If this does work out tell NASA. Perhaps they will build a diorama and have the LEM come in to land on it.
