For the discerning Unmanned Aerial Vehicle (UAV) customer, there are plenty of options available. One such entry into this growing field is the NavMar Applied Sciences Corporation " TigerShark " which is categorized as a multi-role MALE (Medium-Altitude, Long-Endurance) UAV. The TigerShark line currently (2017) exists in two major marks, the original TigerShark and the TigerShark XP featuring broadened capabilities.
Its base design incorporates a centrally-held fuselage fitting the applicable mission equipment, comprised of cameras and sensors, with a high-mounted straight wing mainplane arrangement. The structure also houses the powerplant, avionics and available fuel stores. The tail unit is a twin-boom configuration with vertical fins bookending the horizontal stabilizer. The undercarriage is wheeled and of a tricycle arrangement for ground-running.
The wingspan measures 22 feet and overall length reaches 14.9 fete. Maximum Take-Off Weight (MTOW) is 450lb with a payload capacity up to 75lb. The Tigershark can operate at altitudes up to 14,000 feet and holds a mission endurance window out to seven hours flight time (though this is variable and dependent upon the mission equipment fit and available fuel load). It is powered by a Herbrandson 2-stroke engine of 32 horsepower driving a wood-core composite two-bladed propeller in "pusher" configuration.
The related TigerShark XP model boasts an inherent multi-mission capability covering such roles as data-collection, reconnaissance, surveillance, communications relay, micro-drone controller host, target, Anti-Submarine Warfare (ASW) support and geological / terrain mapping platform. This product sports a "plug and play" feature to make mission payload changes relatively easy. The nose camera installation supports both InfraRed (IR) and Electro-Optical (EO) types. The TigerShark XP flies at up to speeds of 80 knots reaching 15,000 feet of altitude. It has a twelve-hour endurance window and can take-off, fly and land on its own, the latter aided by the onboard laser altimeter and "touchdown" sensors. Payload capacity is up to 100lb.
The TigerShark XP Long Range and Tigershark XP Trainer are further extensions of the TigerShark family line. The former entry is optimized for the Intelligence, Surveillance, Reconnaissance (ISR) role while the latter is optimized for commercial and student UAV flight training. The TigerShark XP Long Range has a noticeably different fuselage design when compared to the other forms.
