The typical bell applicator consists of five major assemblies: the valve module, the bell cup, the turbine, the shaping air shroud, and the electrostatic system.. The valve module is a manifold consisting of passages for paint, solvent, and compressed air, and valves to control the flow of materials for paint delivery, cleaning and purging with solvent or hydropurge, and management of ...
Exhaust resonators are also used to reduce potentially loud engine noise where the dimensions are calculated so that the waves reflected by the resonator help cancel out certain frequencies of sound in the exhaust. In some two-stroke engines, a Helmholtz resonator is used to remove the need for a reed valve.
Work started on the Conway replacement engine in July 1961 and a twin-spool demonstrator engine to prove the HP compressor, combustor, and turbine system designs, had been run by 1966. Rolls-Royce chose the triple-spool system in 1965 as the simplest, lowest cost solution to the problem of obtaining lower fuel consumption and reduced noise ...
Thermal barrier coating (colored white) on a turbine guide vane in a V2500 turbofan engine. Thermal barrier coatings (TBCs) are advanced materials systems usually applied to metallic surfaces on parts operating at elevated temperatures, such as gas turbine combustors and turbines, and in automotive exhaust heat management.
The LM1500 was derived from the J79 engine in 1960. [3] Its first application was for the first US sea-going research hydrofoil, HS Denison. [1] Conversion as a marinised turboshaft engine involved two major changes: the addition of a free power turbine, and corrosion-protection by the addition of internal coatings and a maintenance scheme of freshwater rinsing to prevent salt damage.

A roof turbine ventilator, colloquially known as a 'Whirly Bird' is an application of wind driven ventilation. Passive ventilation is the process of supplying air to and removing air from an indoor space without using mechanical systems.
Robins are a much loved Christmas icon, but wind turbines installed in their habitat are affecting their song, with worrying consequences. Robin hushed: wind turbines are making songbirds change ...
