A recently granted patent (Publication Number: US11919641B2) discloses a side-ways ejection arrangement designed for storing and launching a payload. The arrangement includes a push-out chamber, a launch compartment with an ejection device, an air intake formed in the aerodynamic surface, and an internal air transfer arrangement with an openable closure member. The air intake is configured to transfer airflow to the launch compartment, providing an additional push-out force to the payload during ejection. The ejection force of the device is combined with this additional force, enhancing the launching process.

Furthermore, the patent details an aerial vehicle configured to carry this innovative arrangement and a method for launching a payload using the side-ways ejection arrangement. The method involves loading the payload into the launch compartment, opening the closure member to direct a separated flow of air into the compartment, ejecting the payload with the combined push-out forces, and closing the hatch member post-launch. Additionally, the method includes directing the separated airflow in a specific manner to optimize the launch process, either opposite or obliquely downwards and forwards relative to the flight direction. This patented technology aims to improve the efficiency and effectiveness of payload launching mechanisms, particularly in aerial vehicles, by utilizing airflow to enhance the ejection process.
