Abstract:
A controllable flying airplane includes two separably interconnected modules: a plane module, incorporating substantial airplane style characteristics, comprising a fuselage and a fin mounted thereon with a movable control surface, a component module having a support structure and a set of components mounted thereon including a servo controlled by a control device facilitating controlled flight. At least one pair of mutually magnetically attractive connectors oppositely affixed on said two module members provide means for inter-modular structural connection. A linkage means includes two mutually magnetically attractive linkage portions separably connectable to form a linkage assembly linking said servo and said control surface. The structural connection and the control linkage means disclosed facilitate substantially effortless inter-modular connection to form a controllable airplane as well as nondestructive inter-modular disconnection. Multiple plane modules of differing styles and aerodynamic specifications can be made interconnectable with one component module to form differing airplanes, sharing essential components, for differing applications.

Abstract:
A high performance (high L/D ratio) launch vehicle is tuned for passive or limited control re-entry. In one embodiment, the re-entry vehicle (100) includes a fuselage portion (102) and wing portions (104 and 106) extending from opposite sides thereof. Various vehicle configuration parameters are tuned to allow for passive or limited control re-entry. In particular, the swept wings have a dihedral configuration and the nose of the vehicle (100) is widened. In operation, the vehicle (100) penetrates the outer atmosphere at a high angle of attack and transitions to an aerodynamic angle of attack for substantial cross range and down range control within the lower atmosphere. The vehicle (100) thereby provides for enhanced re-entry safety while reducing propellant requirements, reducing loads and meeting human rating requirements.
Abstract:
A lifting body aircraft suitable for atmospheric flight and/or as a reentry vehicle. The craft has a substantially flat upper surface, a lower surface with a doubly convex first section and a flat sloping second section. Chines may be provided between the upper and lower surfaces. The doubly convex first section allows the craft to have its center of gravity forward of its longitudinal center line. The flat sloping second half of the lower surface and the substantially flat upper surface form the aft end of an airfoil. A pair of vertical stabilizers enhance stability and include rudders which, along with a pair of elevons, provide steerage. The craft may glide or it may have an engine or rockets for thrust. The result is an extremely stable lifting body design that is well suited for launch or conventional take off, insertion, orbital operations, reentry, atmospheric flight, and conventional landings.
Abstract:
A ducted air flow vehicle including a fuselage having a longitudinal axis, a first cockpit on one side of the longitudinal axis, a center portion adjacent and below the first cockpit, a first air flow duct mounted in the fuselage and including a first prime air mover to force surrounding air flow through the first air flow duct, and a second air flow duct mounted in the fuselage and including a second prime air mover to force surrounding air flow through the second duct, where outer upper and lower surfaces of the center portion are aerodynamically shaped to enhance production of aerodynamic lift forces by air flowing over the center portion and reduce resistance to air flow exiting the first airflow duct.
