Have you considered it might be you that's lacking in knowledge rather than the investors and founders? You seem quick to call people out on being scammers for something you clearly don't fully understand. Yes you can cite high school math but than you start making assumptions/assertions, drawing conclusions, etc. that are clearly wrong/baseless. Very sloppy arguing.
You, "leave to the others to calculate how many RPMs should the device make"; like the people behind this company that clearly did that math, build a device and then proceeded to launch an object several tens of thousands of feet up. Clearly their math is better than yours.
"I've not heard of any devices handling 100g over any significantly long periods of time."
You just did.
- culebron21 5y agoLet's give your insult a benefit of a doubt. Show me a complex mechanical device, like a rocket, with fuel tanks, fuel pumps and ball bearings, that withstands >100g continuously for >10 seconds. Turbine blade that has 100g at its tip, is not one. "Don't learn physics, and you'll live in the world of wonders!"
- JorgeGT 5y agoIt is certainly a good question. The closest I found was the guidance and control system for the HARP project (shooting satellites into orbit). According to Wikipedia: The components of the guidance and control assembly were integrated into a 6.25-inch diameter test projectile. Sun sensors, horizon sensors, telemetry packs, receiving/transmitting antenna, hydraulic systems, logic modules, and gas thruster attitude control systems were all test-fired to approximately 10,000 g's https://en.wikipedia.org/wiki/Project_HARP#Martlet_4_Control_Systems https://en.wikipedia.org/wiki/Project_HARP#Martlet_4_Control...
