Helicopter is Stuffed with Compressed Air

(*12*)(*3*)

[Tom] loves to construct little helicopters and made up our minds to construct one that runs on compressed air. (Video, embedded underneath.) Seems it was once a bit of more difficult than he idea. Initially, he was once attempting for a compressed air quadcopter. He’d already labored with an air turbine, however striking on a automobile that may raise itself into the air seems to have a large number of hidden gotchas.

[Tom] went thru a large number of design issues to reach on the helicopter design. He regarded as counter-rotating props, however there have been a bunch of issues concerned. He in spite of everything settled on a unmarried prob with a tail rotor that is living at the a long way finish of a protracted increase to permit the ensuing lever arm to scale back the paintings required of the tail rotor.

One of the vital very best portions of this construct are the check setups. We favored the check rig he has for checking out the thrust of a propeller. It allowed him to keep in mind that his quadcopter design wasn’t possible with the props he had readily available. His schlieren pictures setup was once fascinating, too, and equipped some cool footage of the airflow.

In any case, the effects had been rather disappointing. Alternatively, you now and again be told extra out of your screw ups than your successes. Additionally, an astute iandroid.eu reader would possibly have some recommendation on tips on how to make the flying gadget higher. We really feel adore it could be very shut.

We’ve observed [Tom] (*2*)operating in this in one shape or any other for some time. A few of his air-powered designs are somewhat refined.
