The Propeller Torque Calculator simplifies the torque calculation process, providing a convenient tool for engineers, pilots, and boat owners to estimate the torque generated by a propeller based on its power and speed.
3 Οκτ 2024 · The formula to calculate propeller torque is given by: \ [ Tp = \frac {5252 \times PHP} {PS} \] where: \ (PS\) is the propeller speed in revolutions per minute (RPM). For instance, if you have a propeller with 300 HP operating at 2500 RPM, the propeller torque can be calculated as follows:
Figure 11.24 shows a schematic of a propeller. The two quantities of interest are the thrust ( ) 11.1 and the torque ( ). We can write expressions for these for a small radial element ( ) on one of the blades:
Here we describe the steps in a simple propeller design calculation, using lifting line theory. A table with an example is given afterwards.
2 Ιουλ 2024 · Propeller torque is given as $Torque = c_p * ρ * (\frac{ω}{2π})^2 * d_p^5$, where $c_p$ is the torque coefficient, ρ is the air density, ω is the angular velocity, and d is the propeller diameter.
The first is a demonstration program which can be used to calculate thrust and torque coefficients and efficiency for a relatively simple propeller design using standard linearised aerofoil section data.
11 Νοε 2024 · Calculate the propeller torque (Tp) using engine power and propeller speed with the Propeller Torque Calculator, based on the formula Tp = 5252 × PHP / PS.
