A self propelled free running model is a further addition to the towing tank results.
There are various things that can be observed and tested:• the overall performance and behavior
• course keeping and stability
• stearing ability
• angel of heel, angel of trimm, turning radius
• planing mode
• seakeeping, impact of waves and wind
Following data can be recorded:
• model speed
• propeller rpm
• motor power in Watt
• torque / thrust at propeller shaft
• g- force
How does it work:
we a have a full range of equipment to setup a propulsion system with high efficient brushless electric motors and controllers, steering and trimm devices, regarding the given scale and estimated power.
Shafts for submerged propellers, z- drives, outboardmotors, jetpumps, and surfacedrive units are available as well as a range of bronce or stainless props to fit the right scale.
The models are steered by radio control, so speed steering trimm are controlled proportionaly.
All the installed sensors record in one file. Additionaly the data can be seen in realtime while driving on a screen onshore.
