Research on Landing Impact Characteristic Of Multi-Wheel Bogie Landing gear's Truck
Cao, Xin,Jia, Yuhong,Tian, Jiajie The Society for Aerospace System Engineering 2015 International Journal of Aerospace System Engineer Vol.2 No.2
Taking the four-wheel bogie landing gear as an example, the force status of truck-like landing gear during the landing impact was analyzed and the simulation model of four-wheel bogie landing gear was established. Firstly, a landing gear prototyping model was established using CATIA and imported to LMS Virtual.lab. Secondly, dynamic analysis of the landing impact was simulated with the established model. Finally, with the help of LMS Virtual.lab's parametric design ability, the effects of landing approach and truck pitch angle on the landing performance, truck motion and truck beam strength were studied. These conclusions will be useful to the design and analysis of the truck.

Transition metal phosphides (TMPs) have been widely recognized as an ideal choice for supercapacitors(SCs) due to exceptional pseudocapacitance performance. Otherwise, reasonable structural design ofTMPs can overcome the defects of low rate performance and poor cycle life. Furthermore, the incorporationof carbon materials can enhance electronic conductivity, thereby enabling rapid electron transmission. Herein, we present a novel hierarchical carbon layer coated NiCoP nanoparticles embedded onnitrogen-doped carbon nanotubes (NiCoP/NCNTs), synthesized through a calcination/phosphorizationprocess. By incorporating a carbon layer to anchor nanoscale NiCoP, an increased number of active sitesand improved structural stability are achieved. Furthermore, the presence of NCNTs enhances the electronicconductivity. These combined features result in impressive performance, with NiCoP/NCNTsexhibiting an impressive specific capacitance of 1628.4 F/g at 1 A/g, and good rate capability of 78.5 %up to 50 A/g. Moreover, it also exhibits outstanding cycling stability, maintaining a capacitance retentionof 71.4% after 10 000 cycles. Moreover, the asymmetric SCs based on NiCoP/NCNTs and AC deliver a highenergy density of 45.46 Wh/kg, and exhibit excellent cycling stability of 92.5% after 5000 cycles. Theseresults highlight the potential of NiCoP/NCNTs as a novel battery-type electrode material for energystoragedevices.

In order to achieve iterative design in early R&D period, a Distributed and Real-time Integrated Simulation System for avionics based on a Model-Based Systems Engineering (MBSE) method is proposed. The proposed simulation system includes driver, simulation model, monitor, flight visual model and aircraft external model. The effect of this simulation system in iterative design and system verification is testified by several use cases. The result shows that the simulation system, which can play an important role in iterative design and system verification, can reduce project costs and shorten the entire R&D period.
