The paper presents a wheel dynamometer system developed for testing aircraft landing gear. The purpose of the dynamometer is to measure forces and moments acting on an aircraft landing gear wheel. The dynamometer was designed with the use of strain gages, as an autonomous measuring device, with a wireless data transferring system. The presented system was designed for the PZL 104 Wilga 35A multipurpose aircraft, but it could be re-designed for any other general aviation, light aircraft. The paper contains detailed descriptions of the design and development as well as sample results from early test measurements. Certification for ground and flight tests of airplanes has been considered for the presented dynamometer system.
