In the guide rail type throwing scheme, a load is arranged on a guide rail on the surface of an aircraft, a load engine is started during separation, separation is realized by means of self thrust, and the method is not suitable for separating an externally hung load without a power device. The free throwing is to remove the mounting constraint in the separation process, so that the separation is realized by means of gravity, and the method is only suitable for the throwing process of a large mass load under a specific flight condition. For the external hanging load which has lighter weight and does not have a power device, the gravity of the external hanging load is usually smaller than the lifting force applied by the airflow, and only an ejection type throwing scheme can be adopted.
The potential risks of collision of the thrown object with the aircraft, out of control after throwing and separating the thrown object, disturbance of the aircraft and the like exist in the aircraft load throwing process, and various parameters such as the angle, the angular speed and the like of the thrown object in the separating process need to be determined and verified through wind tunnel experiments. The design speeds of new generation aircraft require experiments to be performed in transonic, supersonic and even hypersonic wind tunnels. From the development progress of wind tunnel equipment in China, the cross section of the current wind tunnel experimental section of the type is small in size, and experiments cannot be carried out by using a true aircraft or an equal-proportion model of an aircraft, so that the corresponding model can be designed for substitution only according to the scaling criterion of the wind tunnel experiment. Therefore, the method has important theoretical and practical significance for developing the catapulting hanger of the throwing object of the aircraft
Therefore, a new model hanging frame mechanism for throwing is developed.

The following relationship can be obtained according to the law of conservation of energy and the relationship of moment angular velocity:
