Unmanned Aerial Systems
The present invention provides an Unmanned Aircraft System, including an integrated unmanned aerial vehicle and all related components and subsystems that can be packaged and transported as a kit, and customized to fit desired mission profiles, and easily repaired by replacement of damaged components or subsystems. The present invention further provides unmanned aircraft system components and subsystems that facilitate low power and low noise operation, and extended flight times.
1 . An unmanned aircraft system comprising one or more of: a launch and recovery module having a removeable rocket motor and a deployable parachute and removeably mounted with the unmanned aircraft system, a fuselage with a mounting feature and wings with mounting features configured to removeably engage the mounting feature on the fuselage, a 6 bladed propeller as described herein, photovoltaics mounted with the unmanned aircraft system, and wingtips removeably mounted with wings of the unmanned aircraft system.
2 . An unmanned aircraft system as in claim 1 , comprising a launch and recovery module having a removeable rocket motor and a deployable parachute and removeably mounted with the unmanned aircraft system.
3 . An unmanned aircraft system 3 as in claim 1 , comprising a fuselage with a mounting feature and wings with mounting features configured to removeably engage the mounting feature on the fuselage.
4 . An unmanned aircraft system comprising a 6 bladed propeller as described herein.
5 . An unmanned aircraft system as in claim 1 , comprising photovoltaics mounted with the unmanned aircraft system.
6 . An unmanned aircraft system as in claim 1 , comprising wingtips removeably mounted with wings of the unmanned aircraft system.
7 . A unmanned aircraft system as in claim 3 , comprising a fuselage having wing mounting features; a plurality of wing sets, each set comprising a matched pair of wings each with mounting features configured to removably engage the wing mounting features on the fuselage, and each with wingtip mounting features; a plurality of wingtips each having mounting features configured to removably engage the wingtip mounting features on a wing.
8 . An unmanned aircraft system as in claim 3 , comprising a wing having a pin, and a fuselage having a receptacle configured to accept the wing and the pin in a removeable mounting relationship.
9 . An unmanned aircraft system as in claim 4 , wherein the propeller is configured to provide 1 lb of thrust at 2,500 RPM with no more than 70 Watts input power.
10 . An unmanned aircraft system as in claim 9 , wherein the propeller is configured to produce less than 70 dB of noise as measured 3 meters from the propeller.
11 . An unmanned aircraft system, comprising an on board power generation system, two power storage systems, and a power management system that apportions power generated by the power generation system among the two power storage systems.
12 . An unmanned aircraft system as in claim 11 , wherein a first power storage system powers a first set of systems of the unmanned aircraft system, and where the second power storage system powers a second set of systems of the unmanned aircraft system, and wherein the second set of systems comprises those systems whose continued operation after a failure of the first power storage system will enable at least one of survival, recovery, or required operation of the unmanned aircraft system.
13 . An unmanned aircraft system as in claim 1 , further comprising an on board power generation system, two power storage systems, and a power management system that apportions power generated by the power generation system among the two power storage systems.
14 . An unmanned aircraft system as in claim 5 , comprising wings formed of a stack comprising a photovoltaic cell and one or more structural layers, with intermediate adhesive layers.
15 . An unmanned aircraft system as in claim 14 , wherein the structural layers comprise carbon fiber core, carbon fiber laminate, or a combination thereof.
16 . An unmanned aircraft system as in claim 1 , comprising a launch and recovery module having a removeable rocket motor and a deployable parachute and removeably mounted with the unmanned aircraft system, a fuselage with a mounting feature and wings with mounting features configured to removeably engage the mounting feature on the fuselage, a 6 bladed propeller as described herein, photovoltaics mounted with the unmanned aircraft system, and wingtips removeably mounted with wings of the unmanned aircraft system.
