The INTRA Defense Technologies "ASEF" is an all-weather / all-terrain Unmanned Aircraft System (UAS) marketed across military, civilian, and industry segments. It is designed to cover many sortie types, whether over-land or in maritime environments, and can fulfill the rigorous mission sets related to tactical reconnaissance, surveillance, threat assessment, border patrol / enforcement, maritime law enforcement, drug enforcement, weather monitoring, high-risk inspection and the like. Its Vertical Take-Off and Landing (VTOL) capabilities give it qualities akin to a helicopter without the complexity, operating costs, and human commitment required.

At its core, the system is an agile and relatively compact solution utilizing a single-boom arrangement with outboard-held lift propellers and a single drive propeller at the aft-end of the fuselage. All pertinent operating components are housed in the centralized fuselage. The mainplanes are seated over the fuselage and the vehicle rests on a simple four-legged assembly. The unit consists of a "V-type" tail.

With a payload limit of 26lb, the complete Asef unit has a Maximum Take-off Weight (MTOW) of 215lb. Performance specs include a cruising speed of 70 miles-per-hour, a mission endurance window of around 10 hours, and a service ceiling rating of 18,000 feet.

The air vehicle utilizes a lightweight, ventrally-mounted real-time camera system with long-range continuous zoom functionality. Video transmission via VSAT is optional while laser illumination and a laser rangefinder are both supported. The data link has a range out to 95 miles. Autonomous functionality is built into the aircraft reduce human involvement during landing and take-off actions. Navigational GPS / INS are triple redundant while systems such as the datalink, electrics, Flight Control Computer (FCC), and data bus all have an integrated dual redundancy quality. A "sense and avoid collision" capability is in-built.©MilitaryFactory.com
