Abstract: Aspects of the technology relate to a braking assembly for a lateral propulsion system of a high altitude platform (HAP) configured to operate in the stratosphere. Power is supplied to a propeller assembly as needed during lateral propulsion so that the HAP can move to a desired location or remain on station. When lateral propulsion is not needed, power is no longer supplied to the propeller assembly and it may slowly cease rotating. However, in certain situations, it may be necessary to cause the propeller assembly to stop rotating as soon as possible. This can include an unplanned descent. Rapid braking can avoid the propeller blades from entangling in the envelope, parachute or other parts of the HAP. A reusable brake is employed to prevent uncontrolled rotation of the propeller on descent, or otherwise to prevent the propeller from spinning freely when not being used to propel the HAP laterally.

Abstract: Based on a difference between target and actual values of a friction member force pressing a brake disc, feedback control over the pressing force is executed. As the actual value, a “limit pressing force (Fbs) obtained by placing a limitation on a temporal change amount of the Fba based on a limit value (Lmt)” is used. The limit value (Lmt) is set based on an electric motor speed (dMkt, dMka), a wheel speed (Vwa), and a temporal change amount (?Tmp) of the friction member temperature. The Lmt is set to increase as the dMkt (dMka) increases and the temporal change amount (?Tmp) of the temperature increases, and to also increase as the wheel speed (Vwa) decreases. Thus, even when a rotating member (brake disc) is deformed, braking torque control can be appropriately executed without accelerating a fluctuation of a braking torque on the wheel.
