Project summary

An experience, gained by the LSPA technicians and engineers in designing of the units, mechanisms and gears for operations in the conditions of the open space and planets, is unique in our industry, and the existing factory equipment also allow to perform the complete cycle of development, fabrication and tests both the inpidual units and mechanisms, and the SC as a whole.

The Project objective is systematization of materials on designs, tests and operations of the Mechanical Friction Units of the Spacecraft and Planetary Rovers (hinges, actuators, mechanisms, and landing gears).

This Project will describe methods of provision of the Mechanical Friction Units serviceability, structural configurations of the mechanisms used in the previous and current space programs, including the planetary landing and self-propelling vehicles.

This document will present the methods of testing of the Mechanical Friction Units as well as the descriptions the structural set ups, available for testing of the Mechanical Friction Units and lubricants.

As a conclusion, this document will summarize a 30-year experience of experts in materials and designs on development of the materials, hard-lubricating coatings, sealings and structures of the Mechanical Friction Units.

The Report document will include the following sections:

- Specialties in operation of the SC's Mechanical Friction Units.
- Review and evaluation of the methods providing serviceability of the SC's Mechanical Friction Units.
- Experience gained in development and operations of the SC's Mechanical Friction Units.
- Review and estimation of SC's Mechanical Friction Units and methodology of designing.
- Experience of developing and using of the special methodologies and facilities for SC's Mechanical Friction Units testing and lubricants used in the space technology.
- Review and evaluation of the lubricants used in the SC's Mechanical Friction Units.
