Although much useful data was obtained on engine removal rates and differentiation of maintenance costs for engines utilized in different aircraft (e.g., the J52-P8 in the A-4E and the A-6E); the data does not yet reflect the new maintenance policy.Jeffreys, D. C...
(4) Wrong method of cost estimation; and (5) Funding problems were critical for causing cost variation, while (1) Inaccurate cost estimation; (2) ... Aziz,R Fayek - 《Alexandria Engineering Journal》 被引量: 43发表: 2013年 Federal Aircraft: Inaccurate Cost Data and Weaknesses in Fleet Man...
Helicopter For balance, the task force also looked at three similar programs with lower profiles and greater success: the Acoustic Rapid COTS Insertion the P8-A Poseidon Aircraft the FSF-1 Sea Fighter Interviews with a variety of experts, as well as background research complemented this analysis....
using different platforms such as microlight aircraft flying high over large-areas [4,20], wind-sensitive and unstable kites [21] and more commonly UAVs [22]. Contrary to most of these studies [1,2,3,4,5,6,7,8,9,10], our contribution (1) uses high-resolution fish eye lens and reg...
These beneficial features have made IN718 a great candidate in the sector of aircraft engines, turbine blades, combustion chambers, and nuclear reactors [6–8]. One major challenge associated with fabricating IN718, however, is the low machinability arising from its high hardness value (372 HV ...
More recently photogrammetry was introduced, using different platforms such as microlight aircraft flying high over large-areas [4,20], wind-sensitive and unstable kites [21] and more commonly UAVs [22]. Contrary to most of these studies [1–10], our contribution (1) uses high-resolution ...
