Remains of guaranteed fuel represent the additional stocks of propellant components in the rocket blocks of the stage of launch vehicles (ILV), designed to compensate for the disturbing factors acting in flight on the LV, and are characterized by carcinogenic and mutagenic effects on the environment. To solve the problem of reducing the technogenic load, a method is proposed for extracting a guaranteed reserve of fuel in the tanks of the worked off stage of launch vehicle. The method is based on the generation of heat due to the combustion of liquefied propane and oxygen vapor directly in fuel tanks. The amount of heat is determined from the condition of evaporation of liquid residues of oxygen and kerosene. The authors have developed a method for extracting the guaranteed fuel reserve in the tanks of the worked off stage in full. The proposed method will make it possible to use the remaining fuel for the controlled descent of the worked off stage.
