Can You Calculate Lift Force for a RC Quad Rotor Helicopter?

Click For Summary

Discussion Overview

The discussion revolves around calculating the lift force for a remote-controlled (RC) quad rotor helicopter, focusing on the role of motors and rotors in generating lift. Participants explore methods for determining lift, including experimental approaches and data sources.

Discussion Character

  • Exploratory, Technical explanation, Homework-related

Main Points Raised

  • One participant inquires about calculating lift force from a single motor for their RC quad rotor helicopter project.
  • Another participant emphasizes that motors do not generate lift; rather, rotors are responsible for lift generation.
  • Some participants suggest that calculating lift is complex and recommend experimental methods or consulting performance data from RC manufacturers.
  • A participant requests guidance on experimental procedures and relevant websites for data, noting difficulty in finding information specific to helicopters.
  • A later reply provides a link to a resource that includes an Excel file for helicopter performance analysis.

Areas of Agreement / Disagreement

There is a general agreement on the distinction between motors and rotors in lift generation, but the discussion includes varying perspectives on the best methods to calculate lift and the availability of relevant data.

Contextual Notes

Participants express uncertainty regarding the specific experimental procedures and the adequacy of available resources for helicopter performance data.

Who May Find This Useful

Hello!
I'm planning to start a project to design a RC controlled quad rotor helicopter. If it works out well I have an idea of making it autonomous. So first thing is that I want to know how to calculate the lift force from a single motor ?

Motors don't generate lift, rotors do. :wink:

It's easier said than done, so I would suggest you do this experimentally and/or using performance data from RC manufacturer websites.

Thanks for correcting me:smile:
What is the experimental procedure? Or can u point me to websites containing this data? I tried searching but I ended up with only RC planes stuff.
