Development of Longitudinal DFCS (Digital Flight Control System) for RSS (Reduced Static Stability)Model Airplane in China

China is now in urgent need of a DFCS for model airplane under RSS condition. The researchresults presented in this paper arc independently obtained as no relevant paper has been found in theworld's open literature.It is obvious that the model airplane should be such as to ensure that the prototype airplane canbe effectively controlled.In addition, the following three important technical measures are taken to guarantee the systemto work properly:(1) Isolation of digital signals from analogue ones; weak current for signal transmission;multi-layer shielding; independent power supply.(2) Special design of an air drop mode without integral so as to ensure the model airplane to beunder proper flight control when airdrop operation is carried out.(3) Minimal lateral deviation of model airplane achieved through remote control.DFCS so designed has already proved successful on more than twelve flight tests. The centre ofgravity can be moved backword 6% of bA (the wing mean aerodynamic cord) with confidence.
