Abstract

An aerospike is adapted to be attached to the front nose of an aerodynamically asymmetric space vehicle system, such as the external tank and orbiter of the space shuttle. The aerospike basically comprises a tapered elongated portion having a first end which is adapted to be attached to the nose of the space vehicle, and a second free end terminating in a substantially rounded disc-like tip member. Use of the spike reduces aerodynamic heating and drag during ascent of the space vehicle into its orbital position, provides an attachment point for tether operations and for propellant recovery, and permits transportion of an external tank into its orbit.
