JG3 Posted January 7, 2022 Share Posted January 7, 2022 The real difference that I was wanting to test this time was the static thrust. Previous testing had found that static thrust gives no real indication of cruise or climb performance. But of course it does make a difference in short takeoff performance. That initial thrust makes a big difference in how quickly the aircraft gets rolling and up to flying speed. With the popularity these days of seeking impressive STOL performance that could be significant. So I purchased a digital load cell and set up a ‘stump pull’ arrangement to give all props equal conditions. The differences in ‘grunt’ are significant, as detailed in the full test results at https://www.stolspeed.com/nid/46 This time also testing a couple of new scimitar-shaped props from Meglin, being imported from the Ukraine by https://www.bushaero.com.au 3 1 Link to comment Share on other sites More sharing options...
