Calculating Propeller Thrust Using Given Data

Click For Summary

Discussion Overview

The discussion revolves around calculating the thrust produced by a propeller during flight, utilizing various provided data points. The focus includes theoretical approaches and practical applications related to propeller performance, efficiency, and the influence of flight conditions.

Discussion Character

  • Technical explanation
  • Exploratory
  • Homework-related

Main Points Raised

  • One participant notes the need for propeller induced velocity to calculate thrust, which is not provided in their data.
  • Another participant mentions that propeller efficiency and thrust are dependent on airspeed.
  • A third participant offers to assist with thrust calculations based on their experience with propeller design and performance during a project.
  • A later reply suggests using specific relationships found in an external resource to solve for thrust, although no details are provided on the equations themselves.

Areas of Agreement / Disagreement

Participants do not reach a consensus on a specific method for calculating thrust, and multiple viewpoints regarding the necessary data and equations remain present.

Contextual Notes

The discussion highlights the absence of certain key variables, such as propeller induced velocity, which affects the ability to calculate thrust accurately. Additionally, the reliance on external resources for equations introduces uncertainty regarding their applicability to the specific situation.

i need to calculate thrust produced by a propeller whilst flying, using the data show below. all equations i have come across require the propeller induced velocity which is not given.

things i know;
-propeller efficiency
-indicated and true airspeed of aircraft
-temp. and pressure at flying altitude
-engine torque
-propeller diameter
-propeller rotating speed

i have tried serching the forum but couldn't find a relevant equation.
 
Physics news on Phys.org
propeller efficiency and thrust are functions of airspeed.
 
Dear buddy,

It takes some iteration to calculate thrust distribution for propeller. However, I can help u to do that coz during my final year project, I've assigned to design and find performance of the propeller itself.

U can give anything that u know abt the propeller, and I will try to help u on that. Email me at solehan85@gmail.com
