While software is now being developed with more sophisticated tools, its complexity has increased considerably, and, as a consequence new vulnerabilities are discovered every day. To address the constant flow of vulnerabilities being identified, patches are frequently being pushed to consumers.

Internal Combustion (IC) engines require Thermal Barrier Coatings (TBCs) to preserve their effectiveness and performance. By coating engine parts with TBCs, thermal fatigue and environmental heat loss may be minimised.

Piston Vibration in Piston-Cylinder Systems
Journal of Fluids Engineering, 1980The motion of a cylindrical piston falling in a liquid filled vertical cylinder is analyzed. It is found that concentric motion is impossible and that flow induced vibration is always associated with such piston-cylinder systems. If the clearance over radius ratio is larger than a certain critical value, βcr, severe wobble and piston-cylinder contact ...

A Novel Axial Piston Pump/Motor Principle With Floating Pistons: Design and Testing
BATH/ASME 2018 Symposium on Fluid Power and Motion Control, 2018This paper presents the first prototype of a novel axial piston pump/motor of slipper type. The pistons are floating in the cylinders and hence the name floating piston pump. The novel pump design fills a gap in the traditional pump design.

The piston ring or the piston seal?
Russian Engineering Research, 2010Improvement in the efficiency of piston compression rings is considered. By taking account of the gas dynamics in determining piston-ring geometry and developing a system of piston rings and piston seals for various internal combustion engines, their basic performance and environmental characteristics may be improved.

Tribological characteristics of piston rings in a single-piston hydraulic free-piston engine
Industrial Lubrication and Tribology, 2017Purpose A free-piston engine (FPE) is an unconventional engine that abandons the crank system. This paper aims to focus on a numerical simulation for the lubricating characteristics of piston rings in a single-piston hydraulic free-piston engine (HFPE).

Study on Piston Motion Control Strategy of Single Piston Hydraulic Free-piston Engine
2012 Second International Conference on Intelligent System Design and Engineering Application, 2012This paper investigates the piston motion control strategies of a single piston hydraulic free-piston diesel engine, which is intended to be a power supply for hydraulic propulsion systems. The Cycle fuel mass is determined by engine displacement and load.

There were a number of aircraft and engine manufacturers active in Germany in 1930s and 1940s. Some were quite well known, e.g., Messerschmitt (former Bayerische Flugzeugwerke), Focke-Wulf, Junkers, Dornier, etc. Some others were rather obscure, e.g., Hamburger Flugzeugbau, Klemmflugzeugbau, etc.
