I had an idea for an exchangeable motor mount system for HPR. Since there's nothing new under the sun, I googled "exchangeable motor mount" and "exchangeable motor mount hpr" and came up empty. A few for LPR/MPR, but nothing for HPR. So, I wonder if, just maybe, this is something new after all. Here's the idea.
In a large airframe tube, add a smaller tube, one "standard" size down or roll your own to a different size. Call that the MMT socket. TTW fins can be attached to the socket. Then the operational MMT goes into the socket. The MMT's forward CR would fit the socket, and the aft CR would fit the airframe tube. Either large T-nuts or threaded studs are installed in aft CR of the socket, and bolts or nuts hold the MMT in. The MMT could have a thrust plate if desired.
Has this been done? Is there a reason it should not be done, such as some much simpler way that I'm overlooking?
