Abstract:
The invention relates to a gyropter having coaxial contrarotating rotating aerofoils, in particular, one having two crown rotors (2,1) that rotate in opposite directions about a pod (6) either provided in the form of a drone or of a manned pod with a machine piloting process involving the control of the angle of attack of the blades by control rings. The safety is advantageously increased by adapted structures, by a multifunctional protective envelop (27), and by a lift system between the crowns (2,1) and the pod (6) with regard to both the radial forces as well as the axial forces, assisting in the optimized control of stresses. The gyropter also comprises electronic controls that are adapted to both model making and drones as well as to manned and/or piloted aircraft.
Abstract:
A flyer assembly (10) is adapted for launching with, transit in, and deployment from an artillery shell (22). The flyer assembly (10) includes a jettisonable shroud (12) and a flyer (14). The flyer (14) is adapted to withstand a launch acceleration force along a flyer axis when in a first state, and to effect aerodynamic flight when in a second state. When in the first state, the flyer (14) is positionable within the shroud (12) with the flyer axis parallel to the shroud axis and the shell axis. The flyer (14) includes a body member disposed about the flyer axis, and a foldable wing assembly (20) mounted to the body member. THe wing assembly (20) is characterized by a plurality of nested wing segments (32) when the flyer is in the first state. THe wing assembly (20) is configurable in an unfolded state characterized by a substantially uninterrupted aerodynamic surface when the flyer is in the second state. The flyer assembly (10) is launched from an artillery cannon, and can thus reach a target quickly, without expending energy stored with theflyer. During launch, the flwyer is coupled to the shroud so as to maintain a portion of the flyer in tension during an acceleration of the flyer along eht flyer axis.
Abstract:
A flyer assembly is adapted for launching with, transit in, and deployment from an artillery shell having a central void region extending along a ballistic shell axis. The flyer assembly includes a jettisonable shroud and a flyer. The shroud extends along a shroud axis, and is positionable within the central void region with the shroud axis substantially parallel to the shell axis. The flyer is adapted to withstand a launch acceleration force along a flyer axis when in a first state, and to effect aerodynamic flight when in a second state. When in the first state, the flyer is positionable within the shroud with the flyer axis parallel to the shroud axis and the shell axis. The flyer includes a body member disposed about the flyer axis, and a foldable wing assembly mounted to the body member. The wing assembly is configurable in a folded state characterized by a plurality of nested wing segments when the flyer is in the first state. The wing assembly is configurable in an unfolded state characterized by a substantially uninterrupted aerodynamic surface when the flyer is in the second state. The flyer assembly is adapted to be launched from a ballistic delivery system such as an artillery cannon, and can thus reach a target quickly, without expending system energy stored within the flyer. During launch, the flyer is coupled to the shroud so as to maintain a portion of the flyer in tension during an acceleration of the flyer along the flyer axis resulting from the launch. The flyer assembly is adapted to withstand the high g-load an high temperature environments of a cannon launch, and can tolerate a set-back g load of about 16,000 g.

Abstract:
Disclosed is a technique for landing a drone using a parachute. The technique includes a parachute deployment system (PDS) that can deploy a parachute installed in a drone and land the drone safely. The parachute may be deployed automatically, e.g., in response to a variety of failures such as a free fall, or manually from a base unit operated by a remote user. For example, the PDS can determine the failure of the drone based on data obtained from an accelerometer, a gyroscope, a magnetometer and a barometer of the drone and automatically deploy the parachute if any failure is determined. In another example, the remote user can "kill" the drone, that is, cut off the power supply to the drone and deploy the parachute by activating an onboard "kill" switch from the base unit.
Abstract:
An unmanned aerial vehicle includes a closely integrated emergency recovery and operation systems for an unmanned aerial vehicle with built-in levels of redundancy and independence to maximize the likelihood of a controlled velocity landing. The unmanned aerial vehicle may include multiple processors and multiple state estimating modules such as inertial measurement units to independently determine the operational and error status of the unmanned aerial vehicle. Base on predictive or projected computations, the emergency recovery system may determine a suitable time for a recovery action, such as parachute deployment, and execute the recovery action.
