How much power is needed to hover ? (REVISED!)

3689669547?profile=original

This article is a theoretical venture that aims to answer a series of practical questions, such as:

– given a certain electrical setup that can generate a certain power, what is the maximum thrust that we can achieve ?

– can a human-powered aircraft be built ?

– can I tell the expected thrust generated by a copter simply by knowing the power it consumes and vice-versa ?

– are larger propellers really more “efficient” ?

– which multicopter configuration is more efficient:  tricopter ,  quadcopter ,  hexacopter or octacopter  ?

– I heard that for every gram of mass I add to my multicopter, the flight time will decrease by 1 second, can you put any sense in this ?

– and many more…

3689410446?profile=originalWhile following William Premerlani and Paul Bizard work (DCM Draft 2) I put together some notes  that I eventually cleaned up and turned into a small tutorial on DCM matrix , orientation kinematics, angular velocity and a IMU algorithm (slighly different from Williams and Paul's) , for anyone interested check it out:
