Aircraft engine performance

Aircraft engines operate in an environment that gets increasingly colder as the aircraft climbs to altitude, so Stirling aircraft engines, unlike any other type of aircraft engine may derive some performance benefit from climbing to altitude. The communities near airports would benefit from the extremely quiet... 

Aircraft and land-based turbines have different performance criteria. Aircraft turbine engine performance is measured in terms of output, efficiency, and...

To be performed in accordance with paragraph titled Tests at 212°F for Aircraft Engine Fuels of ASTM D130r56. Earlier ASTM methods are not applicable since they require a dry sample See 4.5.1 for exception to Method 3251 7 See 4-5-2 for test conditions under Method 3464... 

How chemical coolants work The first use of a chemical engine coolant, ethylene glycol, was tried in England in 1916 for high-performance military aircraft engines. 

A spectacular example of a ridge and valley textile structure, 320 m in length, covers the central concourse of Denver Airport Terminal (1994) and is intended to mirror the snow-capped Rocky Mountains in the distance (Brown, 1994). This is a double-layer membrane used to improve the thermal and acoustic performance of the space (Berger, 2000, pp. 220-221). It is particularly employed to reduce the impact of aircraft engine noise on the interior. As Fig. 7.12 shows, here the distinct contrast between the bright membrane (bright, even though it is double-layer) and the duller surfaces at concourse level can clearly be seen, as discussed previously in Section 7.6.2.
