A wear metal profile is often prepared for each engine. Typically an early wear-in period of high metals concentration is observed, followed by a plateau of low metals concentration [2]. Impending component failure will be indicated by a rapid increase in wear metal concentration, or the sudden appearance of a metal. The metal type and concentration may also indicate to the analyst and engineer...

This paper investigates the performance of U-type pulsejet engine whose overall length is approximately 160 cm. Gas dynamics, acoustics and chemical kinetics were modeled to gain an understanding of various physical phenomena affecting pulsejet operation, scalability, and efficiency. The pulsejet was run in valveless mode on LPG fuel. Pressure, temperature, thrust, specific impulse, and concent...

The Emotion AI Engine is a software “engine” that can simulate and generate “Artificial Emotion” and personality. The core design of the engine is based on the neural and hormonal systems that form the conceptual basis of emotional behavior and the variations between the structure and functioning of those systems that give rise to personality. It is able to simulate and generate a wide range of...

Based on the V-type diesel engine crankshaft system, the paper combined the finite element method (fem) and multi-body dynamics method together, made a virtual simulation analysis. First, by 3d software and finite element software to establish the multi-body dynamic models of the crankshaft, bearing and piston, then simulated the actual engine working condition, and got the data such as cranksh...

Research in this paper is concerned on bay cooling of the new type turboprop engine. The considered engine integration substantially increases temperature inside front nacelle compartment. In order to achieve optimal conditions for parts all operating regimes and engine/nacelle regime after aircraft landing at heat soak-back, a system proposed. Proposed consists standard NACA inlets nacelle, tw...

Interpretation from Concrete Semantics. Static analysis, and type inference in particular, is helpful for finding programming errors in dynamic languages, as they commonly lack the type information available to compiled languages. However, static analysis engines are implemented by hand, hence sharing the challenges of building a symbolic execution engine. To this end, I want to take the “inter...
