Abstract: Hardware-in-the-loop simulation is an effective way and experimental method to evaluate and verify the performance of the aircraft system. To satisfy the requirements of real-time, scalability, high reliability simulation of a certain aircraft control system, a new design of low-cost hardware-in-the-loop real-time scene simulation system consisted of IPC, DSP, three-axis turntable, steering engine and visual simulation computer was put forward. Real-time simulation system software composed by flight control simulation module, aircraft movement simulation module and scene simulation module was implemented, and it resolved the difficulties in real-time, data synchronization, multiple node communication of simulation system. Comparison with …

Abstract: Aircraft ground freezing could lead to potential danger and delay for flight. To alleviate these problems, the main method is to use the deicing fluids to clean ice or snow on the aircraft body, which lacks of reference of the deicing fluids parameters and efficiency. To study the effect of the deicing fluids parameters on the aircraft deicing efficiency, the deicing mechanism is analyzed.The black box mathematical model of the deicing process is generalized abstractly. The deicing process is divided into two subprocesses to establish the deicing model.The relevance between the deicing fluids parameters and deicing efficiency is studied …

The current work delivers the effect of ground proximity on longitudinal aerodynamic forces and the elevator deflection required for trimming the aircraft. The academic understanding states that the with the increasing proximity to the ground,downwash progressively reduces.The methodology adopts the approximation of linear decrement for the estimation of the residual downwash at any height above ground within the unit wingspan. The proposed method utilizes non-dimensional height above ground for the approximation of effective downwash angle in the presence of ground. The approximately predicted effective downwash angle is subsequently utilized to estimate the effect of ground proximity on longitudinal forces, trim …
