Drones 2020, 4, 23 3 of 10 2.2. Aerodynamic Equations Equations (1)–(10), which derive from momentum theory, are based on the work of Allibert et al. [17]. This set of equations provides a method for calculating the quadrotor’s air velocity Using math to easily determine the range of a drone- The range calculation for both fixed-wing and quadrotor can be estimated using the equation below. The kV value is the number of revolutions per minute the motor will turn when 1V is applied to the motor. Quadcopter motor directionThere are 2 directions of propeller rotation: “Props-out” and “Props-in”.

using quadrotor drones [27,28]. All the flight controls of a quadrotor drone are based on variation of the speeds of the four rotors. Hence, a strong down flow occurs during the flight of a quadrotor drone, resulting in vortex and wake phenomena [29], which could interfere with the detection capability of an integrated chemical sensor.

Includes charging cord, spare blades and a small screwdriver. Has a 2.4 GHz transmitter that uses (2) “AAA” batteries. The quadrotor vehicle operates on the concept of variable torques and thrusts. Each rotor consists of a brushless DC motor and rotor with a fixed pitch.

Although quadrotor helicopters and convertiplanes have long been flown experimentally, the configuration remained a curiosity until the arrival of the modern UAV or drone. The small size and low inertia of drones allows use of a particularly simple flight control system, which has greatly increased the practicality of the small quadrotor in this application. The quadrotor is defined by a set of non-linear equations which make accurate simulation as well as control difficult. Once all the components of the equations are developed, it is possible to simplify the equations of motion after making several assumptions about the method which the quadrotor will be operated. A quadrotor helicopter (quadcopter) is a helicopter which has four equally spaced ro-tors, usually arranged at the corners of a square body. With four independent rotors, the need for a swashplate mechanism is alleviated.
