Israel Aerospace Industries or IAI is Israel's prime aerospace and aviation manufacturer, producing aerial systems for both military and civilian usage. It has 16,000 employees as of 2013. IAI is wholly owned by the government of Israel.In addition to local construction of fighter aircraft, IAI also designs and builds civil aircraft and performs local maintenance and reconfiguration of foreign-built military and civilian aircraft. In addition, the company works on a number of missile, avionics, and space-based systems.Although IAI's main focus is aviation and high-tech electronics, it also manufactures military systems for ground and naval forces. Many of these products are specially suited for the Israel Defense Forces needs, while others are also marketed to foreign militaries. Wikipedia.

The presently disclosed subject matter includes a collision warning and avoidance system and method for detecting a collision risk between an interrogating aircraft and at least one interrogated aircraft. Signals received from the at least one interrogated aircraft or by the at least one interrogated aircraft and at least one other interrogating aircraft are used for determining various situation awareness data which is used for determining whether the interrogating aircraft is in a risk of collision. If indeed a collision risk exists a collision warning is generated, the collision warning including data indicative of at least an estimated location of the at least one interrogated aircraft.

A cover assembly is provided, for use with an instrument package having a common aperture. The cover assembly includes an inner cover member and an outer radome member. The inner cover member is substantially transparent to electromagnetic (EM) radiation of at least a first wavelength range. The outer radome member is configured for selectively and reversibly covering the inner cover member and transparent to EM radiation of at least a second wavelength range different from the first wavelength range. The second wavelength range includes a radio frequency (RF) wavelength range. The outer radome member is configured for being mounted in overlying relationship with respect to the common aperture of the instrument package. The outer radome member is configured for being initially in overlying relationship with respect to the inner cover member and for being selectively removed from the overlying relationship with respect to the inner cover member at least during flight conditions.

A propulsion system is provided, including a first propulsion unit, a second propulsion unit, a rotor, a first coupling and a second coupling. The first propulsion unit is configured for being fixedly mounted to an airframe. The rotor is configured for being pivotably mounted with respect to the first propulsion unit to allow selectively pivoting of the rotor from a horizontal mode to a vertical mode. The first coupling is configured for selectively coupling and decoupling the rotor with respect to the first propulsion unit. The second coupling is configured for selectively coupling and decoupling the rotor with respect to the second propulsion unit, independently of the first coupling.

A propulsion system assembly is provided including a driveshaft and a plurality of electric motor modules. The driveshaft is rotatably mounted to a casing about a drive axis, the driveshaft including a first shaft end and an opposite facing second shaft end. The plurality of electric motor modules are in axially stacked relationship with one another with respect to the drive axis to define an electric motor module stack, each electric motor module being configured for transmitting a torque to the driveshaft when coupled thereto independently of at least one other electric motor module. Each electric motor module includes a controllable clutch arrangement for selectively coupling and decoupling the respective electric motor module with respect to the driveshaft to respectively enable and disable transmission of torque between the respective electric motor module and the driveshaft.

A fin deployment system for a projectile is provided, the fin deployment system defining a longitudinal axis and including: an actuator plate, a first mechanical stop arrangement, an actuation assembly, a plurality of fin assemblies, and a second mechanical stop arrangement. The actuator plate is pivotable from a first pivot position to a second pivot position about the longitudinal axis. The first mechanical stop arrangement is configured for initially locking the actuator plate at the first pivot position, and for selectively unlocking the actuator plate from the first pivot position responsive to an actuating force, to thereby allow the actuator plate to pivot to the second pivot position. The actuation assembly is for selectively applying the actuating force to the first mechanical stop arrangement, to thereby unlock the actuator plate from the first pivot position. Each fin assembly includes a fin pivotable from a stowed position to a deployed position about a respective fin hinge defining a respective deployment axis, each fin assembly forming a kinematic pair with the actuator plate such that the pivoting of the actuator plate between the first pivot position and the second pivot position, and the pivoting of each fin from the respective the stowed position to the respective the deployed position, are concurrent. The second mechanical stop arrangement is for locking the fin assemblies in the respective deployed positions responsive to the actuator plate pivoting from the first pivot position to the second pivot position.

Systems and methods are disclosed for providing a controlled temperature in a control volume. Such systems include a main chamber (defining the control volume), a mixing chamber and a gasflow source. The mixing chamber is in selective fluid communication with the main chamber, and has at least one mixing chamber inlet, and a ram air inlet for allowing ram airflow at a first temperature to be channeled into the mixing chamber. The gasflow source provides a source gasflow at a greater, second temperature to the mixing chamber. The mixing chamber provides the mixing chamber outflow at a third temperature by selectively allowing the ram airflow and the source gasflow in the mixing chamber to mix therein, or, by selectively allowing the ram airflow in the mixing chamber to flow to the main chamber (in absence of source gasflow). A controller is operative to provide a desired level for the third temperature.

Images are processed to compensate for rolling shutter effects. A pair of images are registered. A set of pixel rows in the first image and a corresponding set of pixel rows in the second image are obtained. A parametric model is generated characterizing a transformation between pixels in the set of pixel rows in the first image with pixels in the corresponding set of pixel rows of the second image. Using the generated parametric model, the set of pixel rows in the second image is warped with respect to the set of pixel rows in the first image, reducing rolling shutter effects.

An add-on brake system (1) for clamping a wheel disc a vehicle includes a housing (10) accommodating a direct-drive linear actuator, which includes: an electric motor constituted by a rotor (70) and a stator (80); a nut arrangement (73) fixedly and directly coupled to the rotor (70) and configured for revolving therewith; a linear threaded plunger (20) associated with the nut arrangement (73) for being driven thereby in a linear direction upon the revolution of the latter, the plunger (20) having a first end linearly protruding from one end of the nut arrangement (73) and a second end linearly protruding from an opposite end of the nut arrangement (73). The system also includes: at least one inboard brake pad (50) fixedly coupled to the housing; at least one outboard brake pad (60) associated with the second end of the linear threaded plunger (20), oriented transverse to the linear threaded plunger (20) and configured for being driven thereby in the linear direction. The linear threaded plunger (20) has an initial unclamped position in which the second end protrudes to a first extent n_(1) from the other end of the nut arrangement, yielding a first spacing S_(1) between the inboard and outboard brake pads (50, 60), and a final clamped position in which the second end protrudes to a second extent n_(2) > n_(1) from the other end of the nut arrangement (73), yielding a second spacing S_(2) < S_(1) between the inboard and outboard brake pads (50, 60), allowing clamping the wheel disc.
