The discussion revolves around calculating the force required to lift a helicopter, specifically focusing on the mechanics involved in using two fans for lift. Participants also touch on the necessary revolutions per minute (RPM) for the fans and the stability of the design.
Participants express differing views on the questions posed, with some asserting that the force calculation is straightforward while others highlight the complexity of the design and stability issues. No consensus is reached on the best approach to the problem.
Participants do not fully explore the assumptions behind the calculations or the specific conditions under which the helicopter would operate, leaving some aspects of the discussion unresolved.
How are you going to keep it stable? With only 2 fans (and no cyclic control of the main rotor like a full-size helicopter uses), that can be harder. Are you wanting to build something like a drone?SIDDHARTH MANWANI said:
BTW, there is a discussion going on now about the power requirements for drones lifting payloads in this thread: https://www.physicsforums.com/threads/lift-engine.951255/SIDDHARTH MANWANI said:
I don't think you are asking the right questions here. Isn't the force obvious? It's the weight of the helicopter!SIDDHARTH MANWANI said:
