Aviation, or air transport, refers to the activities surrounding mechanical flight and the aircraft industry. Aircraft includes fixed-wing and rotary-wing types, morphable wings, wing-less lifting bodies, as well as lighter-than-air craft such as balloons and airships.

Avionics system suitable for multi-purpose unmanned aircraft

The invention discloses an avionics system suitable for a multi-purpose unmanned aircraft. A 1553B dual-redundancy bus framework is adopted in the avionics system. The avionics system consists of a main processor unit, a universal interface unit, a 1553B bus, a mass memory, an airborne monitoring terminal, a task load, an execution mechanism and a sensor assembly. The devices have the connection relationships that: the main processor unit, the universal interface unit, the mass memory, the airborne monitoring terminal and the task load are connected with the 1553B bus through a 1553B special electric connector, and the 1553B special electric connector serving as a bus module connects all the devices attached to the bus together; a steering engine controller is connected with the universalinterface unit through an RS422 interface; and the sensor assembly is connected to the universal interface unit through interfaces of serial RS422/RS232/RS485, an ARINC429 bus, a CAN, analogue AD/DA and discrete DIO and the like. The avionics system has the characteristics of strong multi-task expandability, multi-redundancy high reliability, rich data interfaces and strong calculation and processing capabilities, and can well meet the application requirement of 'one platform and multiple purposes' of the unmanned aircraft.

Flight program design system for performance-based navigation, verification platform and verification method

The invention discloses a flight program design system for performance-based navigation (PBN), a verification platform and a verification method, belonging to the field of aerial navigation. The program design system is based on an AIXM (Aeronautical Information Exchange Model) core database; a program protection region can be automatically drawn, an obstacle is evaluated, and a chart is generated; and thus, functions such as seamless connection and the like of the PBN program protection region and the conventional flight program protection region can be realized. According to the system, the chart can be automatically generated according to data finished by the flight program design, customized edition and modification can also be realized according to requirement, and program design and publishing are finished at one time. By using the flight program design system, the verification platform and the verification method, the PBN program can be directly added in a navigation database of the verification platform, and the navigation database can be edited and modified in a verification process. In addition, a visual scene database is increased; the defects and the disadvantages of the program design can be directly discovered according to geomorphology in a visual scene when the PBN flight program is verified; and the program is further modified perfectly.
