Steady State Torque for a Quadcopter

Click For Summary
SUMMARY

The discussion focuses on determining the steady state torque for a quadcopter, specifically the counteracting torque applied by the chassis to the motor. It is established that this torque must equal the steady state torque of the propeller but in the opposite direction. The participants clarify that the conventional torque equation, Torque = (Inertia of the prop) * (angular acceleration), does not apply when the propeller operates at a constant RPM, as angular acceleration is zero. A referenced project provides additional insights and equations related to quadcopter torque.

PREREQUISITES
  • Understanding of quadcopter mechanics and dynamics
  • Familiarity with torque concepts in rotational motion
  • Knowledge of steady state conditions in mechanical systems
  • Basic proficiency in interpreting engineering diagrams and equations
NEXT STEPS
  • Research the specific equations for calculating steady state torque in quadcopters
  • Examine the referenced project for detailed torque analysis and diagrams
  • Explore the principles of angular momentum and its application in quadcopter design
  • Investigate the effects of propeller design on torque generation in UAVs
USEFUL FOR

Aerospace engineers, drone developers, and hobbyists involved in quadcopter design and performance optimization will benefit from this discussion.

My partner and I are working on a quadcopter, but we can't seem to find the correct equation we need for the counteracting steady state torque that is applied by the chassis to the motor. Obviously it would have the same magnitude of the state state torque of the propeller, but in the opposite direction. How can I find the state torque of the propeller?

(keep in mind that it is not essentially: Torque = (Inertia of the prop) * (angular acceleration), since the angular acceleration is zero when the propeller is spinning at a constant rpm.

hi
a quick google search turned up this project. someone did a project that involves torque on a quadcopter. hope it helps
http://www.eit.lth.se/fileadmin/eit/courses/edi021/Sammanfattning/2008/LP-4/grupp1/rapport.pdf" The first few pages are not in english but if you scroll down there is a reference section that is in english and explains a lot of things about quadcops and talks about torque somewhere around page 46. it also has some equations and diagrams so maybe you can figure something out from it.

normally i don't think there would be one single generalised equation for steady state torque but i could be wrong.
