Design And Application Of Automatic Control Scheme For Model Rudder Angle Variable Attitude Angle

With the development of modern war,air supremacy competition is becoming more and more important.As for the development of air core fighter,has become a priority among priorities of each country in the field of military scientific research.In today's international situation under the comprehensive national strength,the new generation of fighter R & D budget has been a geometric progression.The United States in the nineties of last century the development of the fourth generation fighter,the F-22 Raptor,its development and production line cost nearly $50 billion,if taking into account the design period of exploration and technology research cost,the total cost up to hundreds of billions of dollars,resulting in its stand-alone cost more than $350 million,higher than the price of 13 tonnes of gold.It is because of a new generation of sophisticated aircraft cost tall look forward to,the use of wind tunnel for aviation equipment,especially aircraft research and development has become the countries are scrambling to develop and use the research means.Although the wind tunnel test is not the only means,but also the current aircraft development threshold is relatively low,relatively inexpensive means to control the cost of R & D.And how to further reduce the cost of wind tunnel test,so that we will be the largest R & D resources,has become a task in front of each of the subjects.The improved test model of rudder surface varying attitude angle,to further reduce the cost of the wind tunnel test,micro motor automatic control way to use more advanced to achieve original technical level can not achieve the effect,through the automatic control of the rudder surface model,complete automatic control of model attitude angle.The scheme is widely applied in the automatic control of the wind tunnel test model,and it can be widely used in various fields such as aerospace,ship,UAVand so on.And the program has been through the test of wind tunnel test and data calculation,the results of the test also proved that the proposed scheme to achieve the intended purpose of the design.
