As discussed in Young and Fryer (2007), thermal bomb approaches (along with alternative, piston-driven shocks) are not intended to embody the physical mechanism that drives the supernova.
Makers of fixed-wing aircraft are also looking at diesel engines, in small planes at least, where they show promise as a serious alternative to standard piston engines, which run on a high-octane form of petrol.The first diesel-powered aircraft, a modified Stinson, took to the air in 1928.
Interest in the use of gas turbines as an alternative to the piston engine had been gaining support in the automobile industry during the 1960s.
Périnet valves were not "derived" from Stölzel valves: they represent an alternative design of a piston valve hence the "Hannah Principle".
However, unlike the lagoon alternative (Fig. 5) piston storage achieves the bulk of its gravitational storage, not by shifting water vertically, but by raising a heavier than water piston.
It is proposed that aluminizing followed by diffusion treatment and nitriding of plain carbon low alloy steels could provide an alternative to the use of expensive nitridable steels for piston ring applications.
In particular, a design strategy is preliminary investigated aiming at replacing the standard aluminum piston, usually manufactured by forging or casting, with an alternative one made of steel and manufactured via an Additive Manufacturing process.
From the published literature it is clearly observed that the effect of using alternative fuel on the design and life and the efficiency on IC engine parts like combustion chamber, liner, piston, piston rings are not addressed.
If I need several million fuel injectors or pistons, an exchange-based market will not be my best alternative.
An animal traction piston press was studied for applications in developing countries, aimed at producing biomass briquettes as alternative household fuel.
"She's a Piston," the tag said.
