Guidance Law Design with Terminal Attitude Constraint for Airborne Dispenser

According to the requirements of airborne dispenser, a closed form guidance law with angular constraint is derived and its project feasibility is analyzed in detail. This guidance law ensure the appropriate terminal attitude angle when dispenser arrives at the open-cabin-point upon the target. Finally, full envelope simulation results from different flight conditions show that the guidance law can meet the requirement of both precision and angular constraint of airborne dispenser.
