Design and Analysis of Delta Wing Tilt Rotor UAV

A tilt rotor is an aircraft of a special kind, which possesses the characteristics of a helicopter and a fixed-wing airplane.\ud However, there are a great number of important technical problems waiting for settlements. Of them, the flight control\ud system might be a critical one. A tiltrotor aircraft comprising a pair of contra-rotating co-axial tiltable rotors on the\ud longitudinal center line of the aircraft. The rotors may be tiltable sequentially and independently. They may be moveable\ud between a lift position and a flight position in front of or behind the fuselage.In this paper we present a project aimed for the\ud designing of a small scale Unmanned Aerial Vehicle (UAV) with Tiltrotor configuration (that uses two rotating rotors). he\ud current paper describes the adopted design methodology, the mathematical and computational models created to represent\ud the UAV, the physical components that constitute the UAV, and the results obtained so far.\ud An unmanned aerial vehicle (UAV), also known as a remotely piloted aircraft (RPA) or unmanned aircraft, is a machine\ud which functions either by the remote control of a navigator or pilot or autonomously. A UAV is defined as a powered, aerial\ud vehicle that does not carry a human operator, uses aerodynamic forces to provide vehicle lift, can fly autonomously or be\ud piloted remotely, can be expendable or recoverable, and can carry payload.India‘s requirement of these unmanned aerial\ud vehicles (UAV) has become prior need for fighting in the northeast, against threat of terrorism, tension along the Pakistan\ud border and its emerging role as a regional naval power and subsequent need for surveillance. The military wants to acquire at\ud least 1,500 unmanned systems in the next 3-4 years, ranging from man-portable drones to high-altitude, long-endurance\ud (HALE) vehicles.Indian military is using Israeli-built UAVs such as the Heron, Searcher Mk II and Harop from Israel\ud Aerospace Industries (IAI). Till date India has mostly deployed medium-altitude, long-endurance (MALE) drones. While\ud the country lags in deployment of UAVs, it wants to develop an integrated program. RUSTOM (English: Warrior) is a\ud Medium Altitude Long Endurance Unmanned Aerial Vehicle (MALE UAV) being developed by DRDO for the three\ud defence services. Indian scientists are still working on its further developments to meet the requirements. This report is\ud basically a case study on the design, development, technology used, working of Rustom and their earlier predecessors. It also\ud includes the advancements which are going to be installed in the upcoming RUSTOM-H, a unmanned combat aerial vehicle\ud (UCAV)
