Collect vibration data

Does Mikado collect vibration data after flight when VBCt / Vcontrol upload data to the cloud? I think it might be helpful for improvement of vibro filters in the next Neo generation based on a big data statistics

Happy New Year!

Hello,

no we don't - the datas were not useful w/o any way more extensive knowledge of heli, maneuvers etc.

Also - "filters" have always two sides ... they probably (and almost) filter also the signal we want to use.

Just try to detect the heli orientation with accelerometers - on a heli with 10-120g shaking noise ... remember - in upright we have 1g on z and 0g onx/y.

So - the pilots and heli manufaturers schould simply take care to avoid vibrations. Even if sensors will get better - the less noise, the better the signal and control quality.

Thank you! Seems that boutique helis like Henseleit and Diabolo just provide less vibration level from airframe mechanical and fbl works in normal state as result = more precision flying.

Hi,

the main cause for vibration are the gearboxes, shape and cut and speed of the gears's teeth, and how they engage/interact, particularly under high load.
Then, long comes nothing, then the drive system (motor/engine with mounted accessories).
Then, it makes a difference if the mechanics/airfraime/rotor head construction can dampen that vibration, and to which degree, and what—as a result—reaches the sensors, and on which axis.

As an example, take any 200-250 size heli (or even 450/470) with normal layout, and with their respective ridiculous head speeds.
They vibrate anything kaputt, sooner or later, and they mess especially with the accelerometers.

Take the LOGO 200 as an example of a direct drive model, no gears but servo gears. The vibration level is 'suddenly' well within the range the sensors there can handle, and even at similarly ridiculous head speeds of up to 7,000 1/min.

The data indeed does not provide much information for general improvement, but being able to see the loads on the sensors is a well-appreciated eye-opener ("MY helicopter has NO vibration, I have YEARS of EXPERIENCE!" :-), as well as a tool to compare changes.
