Claim 9:
10. A method for launching a payload (3) by means of a side-ways ejection-arrangement (1) that comprises an ejection device (4) configured to eject the payload (3) from a launch compartment (5) via a push-out chamber (7) to an airflow (AF), which during use of the arrangement (1) flows over an aerodynamic surface (9) of the arrangement (1), wherein an air intake (13) is formed in the aerodynamic surface (9) and is coupled to the launch compartment (5) via an internal air transfer arrangement (17) comprising an openable closure member (11) configured to close and open the internal air transfer arrangement (17), the method comprises the steps of:
loading the launch compartment (5) with the payload (3) to be launched;
opening the openable closure member (11) for dividing a separated flow of air (SAF) from the airflow (AF) and leading the separated flow of air (SAF) into the launch compartment (5) from the air intake (13), the air intake (13) is configured to transfer flow of air to the launch compartment (5) via an internal air transfer arrangement (17), wherein the flow of air flowing into the launch compartment (5) will affect the payload (3) being ejected with an additional push-out force, and wherein an elect force of the ejection device (4) is added with said additional push-out force;
ejecting the payload (3) from the launch compartment (5); and
closing the openable hatch member (11).
