(i.e. GLOBAL FEM Loads modelling), sub-assembly or detailed component level considering both linear and non-linear cases, Siemens PLM Software offers a proven and most complete solution available on the market to address aircraft structural strength, stability, fatigue, damage tolerance 它是否在...
This paper analyzes the impact of varying downtime and cost of base maintenance checks for aircraft and gives an economic cost-benefit assessment. The reduction of downtimes for scheduled base maintenance checks is complex in terms of technical and logistical aspects. Therefore, the net benefit of...
It should be noted that the average duration for completed sorties is used to estimate how long the next sortie will likely last. When added up (total airborne time for completed sorties + estimate for next sortie), the simulator will order the aircraft to step down if the overall time exce...
Data-driven methods build estimate models based on historical run-to-failure data, which avoid the limitations of relying on physical failure models and expert knowledge [8]. Moreover, data-driven approaches have the advantages of low computing cost and high accuracy. This paper mainly focuses on...
An estimate of the location of the engine may be developed from controllability considerations in emergency situations where one engine is shut down. We consider the specific case of a twin-engine aircraft; the approach may be readily extended to a four-engine airplane. The imbalance of thrust ...
摘要:Multivariate data with small sample in aircraft cost estimation is hard to deal with by the ordinary regression methods. PLSR method can effectively be used to estimate aircraft cost with reasonable accuracy. Through finding out the outliers in observations, VIP analysis, and the explanatory var...

On-design and off-design comparisons estimate the impact of the different mission and vehicle design parameters on the global performance. The paper is organised along this logic: a historical review with the main requirements allocated to HAPS; an analysis of the atmospheric environment; a ...
for preventive protection of the aeronautical heritage. Only the statistical approach from [63] is similar in the application of the Gaussian process, where, however, corrosion of modern aircraft has been predicted, and the surface conductivity of the aircraft is required to measure or estimate. ...
