Abstract:
1. Flying object for transonic or supersonic velocities comprising an aerospike configured as a rod-shaped spike extending in upstream up direction from a front face of said flying object and exposed to airflow; wherein at least a distal end of the aerospike is exposed to the airflow; wherein said aerospike is linked with the flying object such that it is possible to pivot said aerospike during a flight phase of the flying object with respect to an axis oriented transverse to a longitudinal axis of the flying object; wherein said aerospike is mounted with at least one justifying element wherein said aerospike is fixed to a moveable surface; wherein said aerospike, said moveable surface, and at least one justifying element are operative to pivot together as one unit; and wherein said at least one justifying element comprises a surface positioned directly within the airflow such that passive interaction of the surface with the airflow causes pivoting of said aerospike at transonic or supersonic velocities wherein said rod-like spike is fixed to a moveable surface; and wherein said rod-like spike and said moveable surface are operative to pivot together as one unit.
