Research On The Key Technology Of Unmanned Arial Vehicle

Nowadays,the battlefield is complex and the opportunity for combat are constantly changing.The "non-contact,zero casualty" is the combat concept of many military powers.The unmanned aerial vehicles(UAVs)are an important development trend of military battlefield application at the present time.Integrating the function of reconnaissance and strike on the same platform,equipment for battlefield reconnaissance,regional surveillance,the use of airborne precision-guided ammunition for firepower to achieve the "discovery that destroyed",greatly reducing the combat time,is the future of information warfare important equipment.The paper,based on the mission requirements of the UCAV system,investigates the development of unmanned helicopter in the world,and makes the comparison and evaluation of UCAV system indicators.The principle of unmanned aerial vehicle(UAS)In the "reconnaissance and detection" and "reconnaissance and strick" under the system work sequence and process to complete the system top design.For unmanned helicopter platform,the paper models coaxial unmanned helicopter and summary,so that prepares for the control system design foundation.For the purpose of the photoelectric system target positioning,the paper studies the airborne optoelectronic system composition and function,and the principle of autonomous positioning.Based on Monte Carlo method to study the positioning accuracy of the target,analyzes the error source factor and the error source of the impact of the accuracy of the target.For the integration of the airborne weapon system,makes the research of the design of the pylons and the analysis of the flow field of the rotor,as to make the theoretically preliminary research on the compatibility of the projectiles.Finally,based on the system working principle and the combat process,the task deduction software is developed based on STK.This paper is based on the engineering project research,so it has strong engineering practicability,and some conclusions can be directly applied to the project.
