The article discusses research into turboprops being driven by a demand for shorter, cheaper airplane flights. Topics include a brief historical overview of the debut of propeller-driven aircraft, the fuel efficiency of turboprops, compared to turbofans, and engineers at General Electric Aviation's Dowty Propellers, who are using computational fluid ...

This report summarizes the available information on the toxicity of 15 propellants used in aerosols. After reviewing the results derived from various animal species, the following classifications are proposed: Low-pressure propellants of high toxicity: trichlorofluoromethane (FC 11), dichloromonofluoromethane (FC 21), trichlorotrifluoroethane (FC

Chlorofluorocarbon (CFC) propellants used in metered dose inhalers (MDI) must be replaced under the terms of the Montreal Protocol. Following a review of the available data, HFA134a (1,1,1,2 tetrafluoroethane) was selected as a potential alternative propellant.

Experimental study on thermal expansion coefficient of composite multi-layered flaky gun propellants
Composites Part B: Engineering, 2019Improving the burning progressivity is an effective approach to improve the muzzle velocities of projectile of a gun. Composite multi-layered flaky gun propellant is a combination of a fast-burning inner layer and a slow-burning outer layer.
