Strapped to a quadcopter in zero gravity

Click For Summary

Discussion Overview

The discussion explores the feasibility of operating a quadcopter in a zero-gravity environment, particularly focusing on the dynamics of flight when a person is strapped to it. Participants consider the implications of thrust, control mechanisms, and stability in the absence of gravitational forces.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant wonders about the effects of inertial forces on a pilot strapped to a quadcopter in zero gravity, questioning whether they could fly accurately using these forces and visual cues.
  • Another participant inquires about the potential for adjustable pitch propellers on the quadcopter and the range of adjustment, suggesting this could impact flight dynamics.
  • It is proposed that flying in zero gravity is possible, but the control mechanisms would differ significantly from those used in a gravitational environment, potentially requiring software modifications.
  • A participant expresses concerns about stability, suggesting that rotors may need to be reversible or that a wide range of motion for the gimbal mount would be necessary. They also compare the stability of the quadcopter to that of a vectored jet pack.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the feasibility and stability of flying a quadcopter in zero gravity, with multiple competing views on control mechanisms and stability requirements remaining present.

Contextual Notes

Participants have not fully addressed assumptions regarding the design of the quadcopter, the specifics of control systems, or the implications of thrust vectoring in a zero-gravity environment.

I was wondering... imagine a large enclosed space sealed off in intergalactic space, filled with air at normal sea level pressure. I was further wondering with regard to a quadcopter's symmetrical x and y-axis and the fact of the thrust vector always being normal to the plane of the props, that a person was securely strapped to this quadcopter and that it had a decent thrust to weight and was controlled by the pilot with a normal gimbal controller, with yaw and throttle and pitch and roll.

I was pondering that without any thrust it would just float around otherwise the person strapped to the body of the aircraft at the centre of gravity would feel the inertial force of acceleration and so would that pilot be able to fly around accurately merely by relying on the inertial forces they were feeling, assuming there were also plenty of visual cues in the 3 dimensional space in a gravity free zone.

Will your quadcopter have adjustable pitch propellers? If so, over what range of adjustment angle? Why do I ask this? :wink:
 
I don't see why it wouldn't be possible to fly in such a situation. The control would be very different from flying in gravity though, and the software controlling it would probably need to be rewritten.

It would all be very unstable and the rotors would need to be reversible or the pilot would need a 4pi range for the gimbal mount.
Could it possibly be more stable than a vectored jet pack?
