Aerodynamic Forces Relations: U.A.V

External Forces: Listed below are the Forces, acting on the body of air vehicle during flight: Drag Force opposite to VT, D Lift Forces perpendicular to VT, L Side Force, S So L, D, S defines one coordinate system. Transformation: Rotation about y axis by α, and Z axis by β then inverting the components:…

General Velocity Relations : U.A.V

Velocity Relations: Linear Velocity: The true airspeed of unmanned aerial vehicle assumed as Vt, which is calculated by air data system represents the magnitude of flight path vector relative to surrounding air mass.  Flight Path vector aligned with wind coordinate system X axis. In the absence of surrounding air mass movement, the true airspeed can…

Coordinate Systems Transformation : U.A.V

Body Fixed From Inertial: Flight Dynamics is the science behind the attitude or orientations of the aircraft in three dimensions. Rolling, Pitching and Yawing, Angles of rotation about the center of mass in 3D are considered three important parameters of Flight Dynamics. Pitching: The Rotation of an aircraft about the lateral axis is called Pitching….

Ground Control Station, Operational Requirements

Operational Requirements of Ground Control station: We should meet these requirements in to our Ground Control station for getting the reliable operations during missions: The G.C.S should provide visual and audio alerts during the operation as a response to different events, such as a low battery level or a problem with the video transmission of…

Ground Control Station, Functional Requirements

Functional Requirements: For better and safe operation of Unmanned Aerial Vehicle depends upon how we control it with the help of numerous functions: Controlling of Aircraft and Payload: G.C.S should be capable of convey commands to U.A.V for controlling the airborne equipments. Airborne equipments include payload, navigational equipments, Engine and Data-Link. Decision Making: The Autonomous…

Elements of D.R.O.N.E

D.R.O.N.E stands for Dynamic Remotely operated Navigation Equipment. Name itself says that an aircraft with no on board pilot, which can be controlled from Ground Control Station. The outcomes of this aircraft reflect surprising expression on any new comer’s face. Verily, if we want to manufacture this contraption, then we should be able to crack…

Hydrogen Fuel Cell, Long Endurance Solution for Drones

Drones have been implemented in numerous applications as a time and man power saving solution. Applications for Defense and civil, both required drone with good endurance to take out the full mission in one shot. And battery pack was the only solution to power the drone for flying. To solve out the endurance problem, we…

ADS-B, An Air-traffic Surveillance Technology for Drones

ADS-B stands for Automatic dependent surveillance broadcast, a surveillance methodology that enables drones to be precisely tracked by Air traffic controller as well as pilot inside the Ground control station. In this technology, air-vehicle determines its position via satellite navigation and broadcast it periodically. Initially it was implemented in manned aircraft by some developed countries….

GLONASS, A Fail safe Substitute for Drones

GLONASS stands for Globalnaya navigatsionnaya sputnikovaya sistema or Global Navigation Satellite System, an initiative of Soviet Union. GLONASS is a space based satellite system used by Soviet Union Defense forces. During the long autonomous flight, drones totally depend upon Global Positioning System to continue its way-points. If G.P.S receiver fails to receive signals in any…

Controlling of Drones, By Energy

Energy system aka TECS stands for Total Energy control System. Initially, it was implemented in manned aircrafts. The desired outcome directed this idea toward unmanned aircrafts. Simple underlying concept sheaf behind this system includes the balance of gravitational potential energy and kinetic energy. Gravitational potential Energy = mass x gravity x height Kinetic Energy =…
