Ejection seat is a complex system that can be both one-time-used and continuous-used, in which the supportability analysis technology plays an essential role. supportability analysis includes Reliability-Centered Maintenance Analysis (RCMA, for short), Corrective Maintenance Analysis, Level of Repair Analysis (LORA, for short), Operation and Maintenance Task Analysis (O&MTA, for short), support Equipment Requirement Analysis and Spare Parts Requirement Analysis (shortened as '6A'). Firstly, in this paper, the concept of '6A' technology and their relationship are introduced. The general '6A' working process of a certain type of ejection seat is then studied. In the end, the '6A' work is carried out on a certain type of ejection seat according to the analytical steps and requirements to '6A'.

In this paper, the three-dimensional numerical simulation of solid-liquid two-phase flow in a vortex oil filter is performed by means of numerical simulation. The Reynolds stress turbulence model is used in the simulation flow field, and the DPM model is used for solid particle tracking. The influence of key structural parameters and operating parameters on the filtering effect was mainly studied, such as the inlet width, the size of the overflow pipe, the wall thickness and the insertion depth, the size of the cone angle and the length of the cone end. The results provide the basis for the rational design of the vortex oil filter.

Fluid-structure Interactions on Steerable Cruciform Parachute Inflation Dynamics

引用

IOP Conference Series: Materials science and Engineering 2020年第1期751卷

作者： Xinglong Gao Qingbin Zhang Qin Chen Wenkai Wang State Key Laboratory of Aerodynamics China Aerodynamics Research and Development Center Mianyang China Facility Design and Instrumentation Institute China Aerodynamics Research and Development Center Mianyang China School of Aerospace Science and Engineering National University of Defense Technology Changsha China Technology Center AVIC Aerospace Life-Support Industries. Ltd. Xiangyang China

To develop the decelerating and rigging potential performances of cruciform parachute during to its relatively large stand-off with lower cost production in precision aerial delivery operations, the fluid structure interaction behaviours of steerable cruciform parachute is studied. The concept of suspension lines control of cruciform parachute is firstly proposed. Based on the multi-material Arbitrary Lagrange-Euler method, the coupling dynamic model between a viscous incompressible fluid and a flexible large deformation structure of the cruciform parachute is solved. The inflation performance of a cruciform parachute under different steerable conditions is analysed. The decelerating parameters of the parachute, including drag area, and opening loads are obtained from FSI simulation. Meanwhile, the evolution of the three-dimensional shape of the cruciform parachute inflation is predicted.

In order to better study the dynamic characteristics and the control strategy of parafoil systems,considering the effect of flap deflection as the control mechanism and regarding the parafoil and the payload as a rigid body,a six degrees-of-freedom(DOF)dynamic model of a parafoil system including three DOF for translational motion and three DOF for rotational motion,is established according to the K rchhoff motion *** the flexible winged paafoil system flying at low altitude is more susceptibleto winds,the motion characteristics of the parafoil system Wth and Wthout winds are simulated and ***,the ardropm test is used to further verify the *** comparison results show that the simulation trajectory roughly overlaps with the actual flight *** horzontnl velocity of the simulation model is in good accordance with the airdrop test,with a deviation less than0.5m/s,while its simulated vertical velocity fuctuates slightly under the infuence of the wind,and shows a similar trend to the ardrop *** is concludedthat the established model can well describe the characteristics of the parafoil system.
