Patent number: 8168929Abstract: A non-powered pre-stage (10) with a commensurably large wing area is used to launch a variety of single-stage and multiple-stage space vehicles (20), such as conventional ballistic rockets and prospective spaceplanes, from conventional runways. This method of launch eliminates need in dedicated ground launch structures and/or dedicated long runways. The vehicle to be launched (20) is mated to this non-powered aero-assisted pre-stage (NAP) (10), with their flight directions aligned, using a lock-and-release mechanism (30). The resulting stack takes off like a conventional airplane using the propulsion of the vehicle and aerodynamic lift of the NAP. After the desired trajectory of the vehicle is achieved, the vehicle is separated from the NAP and continues its ascent. The NAP returns back to the surface for reuse or disposal. Thus, a wide variety of conventional airfields can be used for launch of ballistic and aero-assisted flight vehicles.Type: GrantFiled: January 15, 2009Date of Patent: May 1, 2012Inventor: Eugene Alexis Ustinov

Patent number: 6540176Abstract: A fin disengagement device for limiting the range of a projectile uses an electronic safe and arm circuit to sense launch and spin levels. Once armed, the stored energy from the electronic safe and arm circuit is dumped into an initiator or directly to explosive bolts. The initiator ignites an energetic material to separate the fin from the projectile in-flight at a predetermined time. Alternatively, the explosive bolts separate the fin from the projectile in-flight at a predetermined time. In the embodiments using an initiator and energetic material, an opening or cavity in the rear portion of the projectile body or rod adapter acts as a pressure chamber. When enough pressure has built up from the burning of the energetic material, the front hub of the fin section expands enough to disengage the threads and separates the fin section from the projectile body.Type: GrantFiled: January 8, 2001Date of Patent: April 1, 2003Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Bradford S.
