How to calculate the weight of a quadcopter?
Simple way about quadcopter weight calculator and thrust calculator are very simplistic calculator base on steady hover, but theoretical calculation is enough for you to bulid a quadcopter. If you have some stories about it, leave your comments. How much weight can a quadcopter carry?
How does the rotation of a quadcopter affect the CG?
Half of the propellers are installed to rotate clockwise (#3 and #4) and the other half counter-clockwise (#1 and #2). Each propeller as it pushes against the air will also apply a torque about the cg of the quadcopter in the direction of its rotation as a function of its thrust, propeller radius, and distance from the cg.
How many propellers does a quadcopter propellers have?
For yaw, the quadcopter takes advantage of its four rotating propellers. Half of the propellers are installed to rotate clockwise (#3 and #4) and the other half counter-clockwise (#1 and #2).
Can a quadcopter be described as a set of differential equations?
In this post we will see how we can describe motion of the quadcopter – or any vehicle – as a set of differential equations. This post is the 2nd in a series on modeling and simulation of a quadcopter’s vehicle dynamics. The full series will include all of the following posts:
How to calculate quadcopter lift capabilities in robotics stack exchange?
This kind of motor has a typical efficiency around 0.7 when on load (if you take a motor with a much higher Kv, you usually decrease its efficiency on load). Therefore, I expect the output mechanical power to be 100W. Mechanical power is speed times torque (checks the units you uses).
How to calculate the lift capability of a drone?
For a given propeller, you can get its thrust vs rpm (round per minute) ratio, so you can get the target rpm (if you have 4 motors and want TWR=2, each motor should achieve a thrust equal to half the drone weight). You can also get its torque vs rpm characteristic, and get the mechanic torque you’ll get at the target RPM.
How to calculate the lift of a quadrotor?
There are mathmatical ways to calculate the lift of your quadrotor but they are a very theoretical approach. You have to think about the enviorment, the wind, air pressure, reaction speed, controlability. I would go further than TobiasK, even if the order of magnitude is correct.
