If you had pressure sensors (red) inside closed containers (black). The one on the left having more air volume than the one on the right. They are inside a bucket (green) that is filled with water. The water will rise higher in the left container. Will the pressure sensor readings be identical...
Would it be possible to send a rocket to Mars containing a number of shaped charges that could be directed at the surface, timed and positioned to direct the excavated material back towards Earth for collection above the atmosphere?
Thank you for your input.
In any case woke up this morning and decided to put pressure sensors on each blade and subtract those readings from the motor reading so problem solved!
I'm building a model as shown below (side, front, back). In order to measure its air resistance I will be mounting it on temporary ice blades (Green) and driving it down a long skating rink. The model has a pressure sensor incorporated into the motor / propeller assembly and a GPS unit to...
Thanks for your replies. I've attached a PDF to better explain the concept and (page 4) to answer your replies. I believe I would need test tank like results to be taken seriously (test bed page 3) but I'm retired now with limited resources. I thought of maybe a crowd funding project? Any...
My question concerns what I call R.P.S. (Rotating Planing Surfaces). This version uses freely rotating disks to plane across the surface of the water somewhat similar to wheels on a car going down the road. Specifically what the lift / drag ratio might be and will it be higher than a typical...
