The featured test bench has been developed within MARC INGEGNOo’s works, with the aim of proving the compliance of our rims and braking  systems  to the Part 21 ETSO requirements, notably those of section C26c.

As part of our technical expertise, it is versatile and adjustable to any future requirements, MARC INGEGNO being the project and software owner and developer.

hrough a configurable torque variator, the energy required by the test – up to max. 0,81MJ per braking wheel – is stored by a 1.4-ton flywheel, which is then properly coupled to the brake disc subject to testing. Similarity to real conditions is thus ensured, as regards the energy amount to be braked and the disc speed. The hydraulic pressure digital control at the caliper sets out the braking process while load cells record the brake torque. The system yields then all digital data, including the disc temperature at both the braking starting point and braking end, braking time, deceleration data, max. torque, compliance to ETSO, etc., along with the relevant charts. 

Our test bench allows for the pressure caliper’s work detailed analysis, for the detection and evaluation of any potential failure. 
The bench is also prepared for the rim endurance tests, providing for alarm adjustment in case of unsuccessful testing. Cyclical testing can also be carried out, along with static as well as braking tests at a continuous temperature or continuous torque – par. 4.1) b); par. 4.1) c).

All our braking systems are accurately characterized during design and engineering, and steadiness of their performance level regularly checked.
