Some aerodynamic problems of guided-weapons

Seven important aerodynamic problems closely related to the development of guided-weapons are analyzed and discussed. The problems are high lift-drag ratio aerodynamic configuration and aerodynamic extended range, multi-wing/fin configuration and its aerodynamic characteristics, rolling control coupling and decoupling of canard-controlled missile, aerodynamic interference of submunition and dispenser during dispensing and. separating, aerodynamic characteristics and radar stealth characteristics of non-circular cross section missile, aerodynamic characteristics of grid fins and lateral jet control technology. It is pointed out that all the aerodynamic problems mentioned above need to be researched more deeply.
