METHOD FOR SAVING THE FAIRING HALF OF A LAUNCH VEHICLE AND A DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2023 - IPC B64G1/62 

FIELD: rocket and space technology.

SUBSTANCE: rescue method is based on the controlled movement of the fairing half (FH) using the onboard control system with periodic correction of the calculated parameters of the movement of the center of mass. A propulsion system with gas-jet nozzles and a controlled parachute system are used. At the apogee of the flight path of the FH, a corrective impulse is introduced into the motion control program. The program parameters for correcting the movement of the center of mass, the angles of attack and the power angle of roll of the FH are determined from the condition of permissible fuel consumption of the propulsion system, and the kinematic parameters of the FH movement at the time of parachute opening are determined from the condition of the optimal kinematic parameters of the parachute insertion area and coordinates of the landing point. After opening the parachute, momentless discharge of fuel residues of the propulsion system is carried out through gas-jet nozzles. The rescue device includes a controlled parachute, a system for controlling the FH movement with actuating elements, a system for introducing a parachute and separating from the FH upon landing, a container with compressed gas, a container with hydrogen peroxide, valves, and catalysts.

EFFECT: expansion of the range of points of fall of the FH by the required values in a certain range and the preservation of the energy-optimal launch trajectory of the launch vehicle without creating new areas of fall.
