Steady State Torque for a Quadcopter

AI Thread Summary
To calculate the steady state torque of a quadcopter's propeller, it's essential to understand that it counteracts the torque produced by the chassis. The torque of the propeller can be derived from its thrust and the distance from the center of rotation, but it is not simply calculated using angular acceleration since it remains constant at steady RPM. A referenced project provides insights and equations related to quadcopter torque, particularly around page 46, which may aid in understanding the dynamics involved. There may not be a universal equation for steady state torque applicable to all quadcopters, indicating the need for tailored calculations based on specific designs. This discussion highlights the complexity of torque dynamics in quadcopter design.

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.
 
Engineering news on Phys.org
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.

Here's a video by “driving 4 answers” who seems to me to be well versed on the details of Internal Combustion engines. The video does cover something that's a bit shrouded in 'conspiracy theory', and he touches on that, but of course for phys.org, I'm only interested in the actual science involved. He analyzes the claim of achieving 100 mpg with a 427 cubic inch V8 1970 Ford Galaxy in 1977. Only the fuel supply system was modified. I was surprised that he feels the claim could have been...
Thread 'Turbocharging carbureted petrol 2 stroke engines'
Hi everyone, online I ve seen some images about 2 stroke carbureted turbo (motorcycle derivation engine). Now.. In the past in this forum some members spoke about turbocharging 2 stroke but not in sufficient detail. The intake and the exhaust are open at the same time and there are no valves like a 4 stroke. But if you search online you can find carbureted 2stroke turbo sled or the Am6 turbo. The question is: Is really possible turbocharge a 2 stroke carburated(NOT EFI)petrol engine and...
