The work presents the idea of a valve equipped with an amplified piezoelectric actuator (APA® - Cedrat Technologies), designed for the use in an adaptive pneumatic shock absorber, which is considered as a landing gear of a small aircraft or unmanned aerial system. The idea of adaptation to impact conditions is based on the controlling the fluid flow between two chambers of the absorber. In the considered method flow intensity through the valve determines the absorber reaction. Utilization of the piezoelectric active element (APA) allows for fast acting of the system. A prototype of the valve and the absorber were created. The tests of the mass flow rate were performed.
