Main Engine

The process of reviewing test data for anomalies after a firing of the Space Shuttle Main Engine (SSME) is a complex, time-consuming task. A project is under way to provide the team of SSME experts with a knowledge-based system to assist in the review and diagnosis task. A model-based approach was chosen because it can be adapted to changes in engine design, is easier to maintain, and can be explained more easily. A complex thermodynamic fluid system like the SSME introduces problems during modeling, analysis, and diagnosis which have as yet been insufficiently studied. We developed a qualitative constraint-based diagnostic system inspired by existing qualitative modeling and constraint-based reasoning methods which addresses these difficulties explicitly. Our approach combines various diagnostic paradigms seamlessly, such as the model-based and heuristic association-based paradigms, in order to better approximate the reasoning process of the domain experts. The end-user interface allows expert users to actively participate in the reasoning process, both by adding their own expertise and by guiding the diagnostic search performed by the system.

Basic Understanding

This paper reviews the technology of the tribological components of engines and presents a basic understanding of their design and operation. The availability of this basic understanding is put forward as an essential counterpart to computerized performance analysis programs for components with variable loads and speeds, such as crankshaft bearings, piston rings and cams and followers.

A new layout of a two-cylinder internal combustion engine with counter-pistons is proposed, which increases its efficiency by reducing the pressure angles. The dynamics of the proposed arrangement of a two-shaft crank-slider internal combustion engine, which provides maximum torque moment at maximum gas pressure in the minimum volume of the combustion chamber, is investigated, which reduces the load on the engine design and its weight and dimensional parameters. The research was carried out by comparing the dynamic characteristics of different engines using vector modular models and the KDAM program.
