And if the C919 could prove it’s safe, reliable and fuel-efficient in commercial operations, and has a competitive price, it will of course be welcomed by the global market.【1】What does the C919’s certification meanA.Chinese aircraft manufacturing ha superior to American.B.The C919 is ...
提交时间:大约 1 年以前 A major independent flight tracking platform, which has made enemies of the Saudi royal family and Elon Musk, has been sold to a subsidiary of a private equity firm. And its users are furious. ADS-B Exchange has made headlines in recent months for...
Typically, the multi-point injection system uses a swirler (e.g., the axial and radial swirlers constitute the flow path into the fuel injection area), which affects the location of the injection point and the crossflow conditions near the fuel injection point [32–35]. A comparison of ...
The experimental plan was conducted with fuel blends of Jet A1 and biodiesel using the biodiesel volume contents (wBD) of 0% (BE0n)e,rg5i%es 2(0B159),,1a2n, xdF1O0R%PE(BE1R0R)E. VTIhEeWblends were prepared in a tank with a nominal capacity of 4 m3, us3inofg11 a transfer...
It was also concluded that the fuel enrichment near the flame stabilization region reduced the base blowout equivalence ratios significantly. Flames stabilized by a bluff-body had the features as flames with a central pilot, under which conditions the outer flow was mainly un-burnt due to the ...
This aromatic-containing jet fuel has been approved to be blended with Jet A1 conventional fuel in amounts up to 50 vol% [72]. 3.3. Alcohol to Jet Fuels As shown in Figure 4, the ATJ route involves three main steps: (i) dehydration of the bioalcohol to the corresponding olefin; (ii...
To get rid of these effects in the iSTC-21v engine, it would be necessary to replace the fuel nozzles and improve the fuel supply system. These oscillations could be attenuated by the controllers by increasing the response times of the controller, however, this would go against the design ...

Faculty of Aeronautics, Technical University of Košice, 041 21 Košice, Slovakia * Correspondence: rudolf.andoga@tuke.sk Abstract: One way to efficiently control the fuel flow of small turbojet engines is to use direct control of the speed of a suitable electric fuel pump, as opposed to ...
When H/D is small, the wall attachment effect of the jet and the boundary layer effect generated at the bottom of the fluid domain have a certain role in maintaining the velocity of the jet near the wall, resulting in a significantly higher axial velocity than other H/D conditions, up ...
