Abstract One of the major problems in development algorithms for monitoring life aircraft gas turbine engines is that character loading real flight cycles crucially different from static and dynamic during testing samples. This paper proposes a method taking into account effect retentions at maximum stresses cycle temperatures on low-cycle fatigue (LCF) heat-resistant alloys used engine parts. ...

At high speeds and under large axial forces, the disc–drum combined structure exhibits inconsistent deformation between parts. The difference in structural characteristics of different parts, speed, preload, its distribution mode, along with other factors, make parts more complex, resulting during work; this inconsistency has a direct impact on engine performance. This paper presents systemic i...

1.6L OHV “KENT” ENGINE Open-wheel racing enthusiasts associate this overhead valve design with the long-lived international Formula Ford series, the starting point for many professional drivers. Most of the combustion chamber is in a dished piston, where the mating cylinder head face is nearly flat. Production for European models (Cortina, Capri and Fiesta) is now phased out. Ford Racing sold n...

In this paper, an algorithm for datadriven incremental learning of fuzzy basis function networks is presented. A modified version of vector quantization is exploited for rule evolution and incremental learning of the rules’ antecedent parts. Antecedent learning is connected in a stable manner with a recursive learning of rule consequent functions with linear parameters. The paper is concluded w...

Developed in the context of virtual environments linked to artistic creation, Egosound was conceived to visualize multiphonic sound space in an egocentric way. Ambisonic algorithms and a graphic editor for trajectories are implemented. An example of artistic project with Egosound is exposed. Parts of the software engine of Egosound are now available for download as external objects for Pure Dat...

In the paper the weak points of today's reciprocating compressors arc described. Referring to latest internal combustion engine technologies and improvements, some possible application on reciprocating compressors will be described and discussed as: • Application of advanced Electromechanical Valves (EMV) with fully variable valve actuation in order to increase compressor speed ("downsizing") a...

Discrete event simulation has traditionally been defined by items (or entities). This modeling paradigm has served the simulation industry well, but falls far short for many industries in which the parts / pieces mindset simply does not accurately portray their particular processes. For the last ten years Simulation Dynamics has been working with industries where the item paradigm falls short a...

The 68HC12 is the latest family of Motorola 8-bit microcontrollers. It is upward compatible from the 68HC11 (at the source code level but not the object code level) but contains many new instructions and addressing modes which considerably enhance its speed and code efficiency. This paper describes the implementation of a subroutine-threaded Forth called WHYP on the MC68HC812A4 and MC68HC912B32...
