Air Pressure Sensors on Vario


Volker,

Fantastic coverage of the Logo meet. I spent a long time going over the videos and still pictures. One of the things that caught my eye was the heli with air pressure sensors fore and aft of the swash plate. I could make out the the blade grips were Vario, but I am not sure of the rest of the heli.

From the position of the sensors it looks like the rotor wash air velocity is being measured, however I woud like to know why this information is important and what is is used for?

Regards,

Jon.

Hi Jon,

the heli you are talking about is a homemade 32 cell heli from Ulrich Roehr (www.ulrich-roehr.de) powered by an actro 40-4 motor. He use the air sensors (and of course a little self developed electronic) to simulate the flybar so that the heli fly with a rigid head like a flybar head. He also use a little data terminal to configure about 50 parameters to the electronic in the heli.

Wow. Great videos and pictures! I've never seen so many videos ready to view on one page! BTW, I've never heard bass come from my computer like that! (on first video...) Sometimes the video recording rate is so well timed to the rotor blades, that just by chance it looks like the helecopter is lifting off the ground by some strange force! Oh no! The blades are barely moving!
