The invention relates to a flying object being moved with transonic or supersonic velocities. Known flying objects comprise so called "aerospikes" used for reducing the wave drag and improving the airflow at the front surface of the flying object. The positive effect of these aerospikes is decreased or cancelled in case of the flying object moving in the airflow with an inclination angle between the longitudinal axis of the flying object and the aerospike. The present invention suggests pivoting the aerospike by means of active or passive measures in order to align the aerospike with the upstream airflow during a flight phase of the flying object.
