VZLU is developing cooperation with industry through the TRIO program

The "Wheels and Brakes" project was one of the successful projects. Its main objective is to create prototypes of a wheel and a brake for chassis of small and medium-sized aircraft up to a maximum of 25 passengers and a weight of up to 7.5 tons. Prototypes of wheels of the main chassis and wheel brakes will be developed as part of the project.

Prototypes will be designed for aircraft weighing approx. 4.5 tons with a guiding speed of about 235 km/h., braking about 195 km/h, and braking energy of about 5.6 MJ.

Brakes are hydraulically operated. Concerning the wheel, the material of wheels, seals and position in bearings will be solved. The problem of signaling the thermal load of the wheels by means of fast temperature sensors will be solved. It will also address the optimization of wheel and brake designs in terms of heat dissipation from the friction pair of both the brake and wheels. In addition, highly durable brake linings will be developed to increase reliability. Prototypes will be tested to the extent that they are approved for use in aviation.

Besides the VZLU, the Polytechnic University of Jihlava is also involved in the project. The main beneficiary is JIHLAVAN. The total subsidy for the project is about 14.4 million CZK. Its activities started already on January 1, 2018 and will run until the end of June 2020.

The "Thermoplast" project is another project financed by the MIT. The main beneficiary is LATECOERE, a company engaged in the production and development of parts from high-tech reinforced thermoplastics since 2005. The intention is to use the experience and knowledge gained from previous projects in the development of specific parts, especially the most proven computational and simulation procedures and technological and construction solutions.

The project focuses on the development of real parts of the aerospace structure in the shape of a reinforced thermoplastic profile. The aim will be designing a suitable shape, dimensioning and finding optimal production technology for selected parts shapes. Specifically, it is a horizontal beam and a vertical frame of the transport aircraft door and a T profile as a replacement for titanium in the airframe ribbing assembly. The purpose is the research and development of new technological processes to achieve cost-effective design of selected parts. A benefit to the beam and the frame will be a significant reduction in production time compared to existing thermosetting matrix composite technology. Door profiles are considered for a new generation door, but the vertical frame has a chance to be used as an alternative to the already made doors for the Boeing 787.

The Czech Technical University in Prague (ČVUT) is also involved in the project together with VZLU and LATECOERE. The total subsidy is almost 12.2 million CZK. The project commenced on January 1, 2018 and will end on December 31, 2020.
