Welcome to the home of Precision
on-site propeller balancing and vibration analysis for UAVs, drones, autonomous aircraft, both civilian and military
is where you can find the most precise, accurate analysis and balancing
of your propeller/motor combination. We're a mobile service and will travel to your company or to
an airport conveniently nearby. We're fully insured to work on UAV/drone power units and that is our specialty.Our technician's hands-on aviation technical experience spans 50 years and a range of aircraft from cold-war era jet fighters and bombers to modern airliners and general aviation (GA) piston aircraft.
We no longer perform balancing on general aviation aircraft (Cessna, Piper, Beech etc). However, havng successfully balanced well over 600 of these GA aircraft, over a 14 year span, we have a wealth of knowledge about the intricacies and tricks and traps associated with both static and dynamic balancing.
Unlike those regular aircraft, drones and UAVs are extremely challenging to balance because, for example during hover, the speed of each motor is constantly varying in order to maintain a level attitude..
It takes many runs to bring the imbalance of each UAV or drone motor and prop down to close to zero. It also takes many judgements by a skilled expert during these runs in order to get these propellers to be in balance throughout their wide speed range.
So it's nothing like balancing a regular aircraft, where there is a steady cruise speed at which we need to have a smooth motor and prop. hovering UAVs, drones, autonomous aircraft need to be extremely smooth throughout a very wide range of speeds. That requires that the person doing the balancing be expert at tricking the assembly into complying.
WHY IS IT SO DIFFICULT AND COMPLEX?
Because vibration comes from a variety of sources and is difficult. but not impossible, to cure.
Just looking at a mass imbalance, for example, when you apply a corrective weight to the propeller hub this weight is only good for a specific narrow range of RPMs.
For example, putting a 12 gram weight somewhere on the hub might be the perfect amount to use at 2000 RPM but it could easily be too much or too little at a higher RPM. Also there will be not just one but several mass imbalances around the hub, each requiring a corrective weight. These can and will interact with each other to give you a
situation that is very difficult to resolve - unless you've seen hundreds or thousands of these and have developed the skills to get around the laws of physics enough to make the propeller assembly useable for your purposes.
First, however, the sources of vibration must be clearly identifed and each treated differently.
