In single-action mechanisms for rocket and space applications, torsion bars in the form of torsion shafts are used as actuators to ensure the deployment of individual components or parts of aircraft before they are locked in place, in addition to torsion springs. With regard to aircraft mechanisms, a design calculation of torsion bars was considered, which made it possible to determine the range of design values for torsion bars based on specified initial parameters, within which the strength condition is met, as well as to ensure the search for optimal solutions for torsion bars when designing aircraft mechanisms with the required performance and reliability. Based on the design calculation, a torsion bar calculation program has been created and used in the EXCEL package, enabling rapid identification of optimal solutions for use in aircraft designs.
