摘要： An embodiment of an antenna includes first and second transmission lines, first antenna elements, and second antenna elements. The first transmission line is configured to guide a first signal such that the first signal has a characteristic of a first value, and the second transmission line is configured to guide a second signal such that the second signal has the same characteristic but of a second value that is different than the first value. The first antenna elements are each disposed adjacent to the first transmission line and are each configured to radiate the first signal in response to a respective first control signal, and the second antenna elements are each disposed adjacent to the second transmission line and are each configured to radiate the second signal in response to a respective second control signal. Such an antenna can have better main-beam and side-lobe characteristics, and a better SIR, than prior antennas.

摘要： Particular embodiments include a non-dedicated, temporarily installed, airborne special mission payload mounting system which is mechanically interfaced to the Air Deployment System (ADS) rails of a host cargo aircraft. An Adaptive Mounting System (AMS) plate is placed over an ADS rail section and restrained in position. Once the AMS plate is secured, an articulated or fixed position strut can be attached to the AMS plate through the opened side doorway without removing the original door. A removable load transfer brace (LTB) can be coupled from the AMS plate inboard to the floor of the aircraft. The LTB is hinged to the AMS plate, and can be disconnected from the floor of the aircraft and rotated to a vertical position from the AMS plate.

摘要： Aircraft antenna fairing assemblies include a fairing shell and connection components for positionally fixing the fairing shell to airframe structure of an aircraft. The connection components may comprise a guide assembly having a guide head and a receiver defining a guide channel for receiving the guide head therewithin, and a latch assembly for latching the fairing shell to the airframe structure of the aircraft. The receiver of the guide assembly may define a generally C-shaped or generally U-shaped channel for receiving the guide head therewithin.

摘要： The present invention aims to provide a structure which can reduce the scale of modification of an airframe and allows a device to be installed outside the aircraft to be easily mounted onto the airframe. An aircraft includes, as a structure for mounting a measuring device to be installed outside the aircraft onto the airframe: an arm which penetrates the airframe inwardly and outwardly through a window, and has a portion to be provided with the measuring device and a portion located inside the aircraft; seat rails which support seats disposed inside the aircraft; and a mount which is connected with the arm inside the aircraft and transmits a load input from the arm to the seat rails.

摘要： An imaging radar system for an aircraft includes four transmit antennas, connected to a central transmitter, and four receive antenna arrays for respectively receiving reflections of signals transmitted by the transmit antennas. A receiver circuit, associated with each antenna element of each receive antenna array, heterodynes the received signal to yield a resultant signal and combines the resultant signal with a reference signal to yield an interference grating signal. The grating signal of each receiver circuit is digitized and provided to a central processing unit that performs a spatial Fourier transform on the grating signals to determine angles of reflecting objects relative to each receive array.

摘要： A passive load mitigation system for supporting transducers on a body moving through a fluid stream is described. According to the invention, a streamlined aerodynamic surface for supporting the transducers is attached to the body via a pivot axis. The axis supports the surface in a torsionally unrestrained manner in at least one rotational degree of freedom about the pivot axis. Therefore, as the body moves through the fluid stream, the surface remains substantially parallel to the plane of the stream. Aerodynamic stability is ensured by forming the surface with substantially trapezoidal or parallelogram shaped sidewalls and by mounting the surface on the pivot axis such that the surface's aerodynamic center is located downstream of the pivot axis. Flutter is prevented or substantially reduced by increasing the surface's bending stiffness or by incorporating ballast weights on a tip pod attached to a portion of the surface.

摘要： A tethered drone system has a drone that carries telecommunication equipment, such as one or more cellular transceivers and an antenna, that enables the system to provide access to a telecommunication network for a plurality of remote communication devices in a vicinity of the drone. The drone may be disassembled to facilitate transport to a location at which additional cellular service is desired, such as a remote location or an area impacted by a catastrophic weather or geological event. At or near such location, the drone may be quickly assembled and launched. While airborne, the drone may hover for an extended period of time, such as several, hours, days, weeks, or even longer, while the telecommunication equipment carried by the drone provides access to the telecommunication network.
