In order to accurately analyze the performance and influence of landing gear system
this paper presents a high fidelity plant model of an aircraft landing gear to inclusion into a full aircraft flight simulation. The use of domain specific modeling software enables detailed modeling of the physics and facilitates accurate computational simulation of the flight dynamic
aerodynamic
landing gear dynamic and mechanical loads that occur when the landing gear are deployed and retracted during landing and take-off operations. The parameter design space is easily searched by considering a number of different landing scenarios including touching down on one wheel first
to optimize the design. The simulation results show that the aircraft landing gear system mathematical model established appropriately reflects the change of force and moment in the process of taking off and landing
and it is improve the precision of flight simulation. 2011 IEEE.

In order to meet special requests of optical imaging sensor in scene matching navigation system
a disc varifocal mechanism is proposed for the flight vehicles of long flying time and range. Within small space occupied
it can obtain real images with various resolutions. Moreover
using plate traveling-wave Ultrasonic Motor as its driven motor can reduce energy loss
improve control precision and ensure image obtaining being real-time and stable. Disc varifocal mechanism driven by plate traveling-wave Ultrasonic Motor is high-response
and variation in load doesn't affect its performance parameter. Therefore
applying disc varifocal mechanism in scene matching navigation system
combing software and hardware
can obviously improve the accuracy
real-time and robust of scene matching navigation system. The experiment showed that when the weight of mechanism was 1.5kg
the shortest starting was 0.6ms
and the shortest shutoff was 0.5ms. 2009 IEEE.
