Case Study for“Fire Practical Test for md4 Body”

Company profile

The company microdrones GmbH was founded in October 2005. All founders had been engaged withdevelopment of aerial vehicles for several years. The innovative fusion of our core expertise is our formulafor success.

microdrones objective is the development and production of rotary wing based VTOL MAV´s. (VTOL =Vertical Take Off and Landing, MAV = Micro Aerial Vehicle)

The first product, the md4-200, is available since April 2006. The microdrone md4-200 is used in many

applications. The newest microdrone is the md4-1000 which has outstanding capabilities. It is the mostefficient UAV in the 5.5 kilo class. With flight times of up to 70 min. and payloads up to 1200g it definitelysets new standards. With future products microdrones will introduce even much more sophisticated control-and communication technologies

Situation, aims and objectives

The VTOL UAV md4 systems of microdrones GmbH are used for public authorities (e.g. police and firefighters) and in industrial applications world-wide. Furthermore, universities and official project offices trustthe md4 platforms and its features such as the open interface.

Motivated by the project AirShield, microdrones faced the challenge to test its products for their resilienceagainst heat and flame at the German "Federal Institute for Materials Research and Testing".

The goal was clearly defined:In particular, operations for authorities in the field of fire and industry inspections, the carbon fiber body,carbon fiber arm and the engines and rotor blades made of carbon fibers needed testing to the extremerequirements for flights close to fires in regard to operability and reliability.





Solution

The results were impressive: The microdrones arms had to withstand the tough test twice for half an hour.Once with and once without the rotor blade.

With success: approximately 450°C were measured outside of the carbon fiber structure. Inside it, on themotor circuit board temperatures up to 150°C have been recorded. The carbon fiber arm withstands theheat, the engine is reliable and performs as expected.

The excellent results are entirely due to the intensive R&D programs of microdrones. Years of intesiveresearch and testing as well as consistent development and last but not least the close cooperation of theresponsible staff having created a powerful product that is currently the most advanced technology on themarket you can get.

Benefits

The only VTOL MAV in its class, which has officially passed a fire test

Especially tested for the use in extreme areas of applications

Reliable VTOL MAV for the use of public authorities (Police / Fire / Emergency Services)
