“…So parafoil and payload exhibit independent rotational motion and hence the parafoil-payload system needs to be modelled as a two body problem. Thus an accurate model contains atleast nine degrees of freedom, three degrees of freedom for the rotational motion of the canopy, three degrees of freedom for the rotational motion of the payload and three degrees of freedom for translational motion of the confluence point (Prakash et al (2006)). Slegers et al (2008) used a 6DOF model to achieve direct longitudinal control through variation incidence angle.…”

“…Slegers et al (2003) used a 9DOF model to study the control issues for a parafoil system with left and right brakes used as the control mechanism. Prakash et al (2006) used a 9DOF model to analyse gliding and turning flight of parafoil system subjected to change in left and right brake deflections. Gorman et al (2011) compared models ranging from six to nine DOF.…”

“…An accurate model having nine degrees of freedom, modeled as two-body dynamics, consisting of three degrees of freedom for rotational motion of the Parafoil, three degrees of freedom for the rotational motion of the payload and three degrees of freedom for translational motion of the Parafoil 14 . The turning and gliding flight of Parafoil system is analyzed by Prakash et al 14 subjected to change in left and right brake deflections. This, nine degrees of freedom model incorporates nonlinear aerodynamics to predict all kinds of behavior.…”

The biggest problem oil and gas industry facing today is the safety and security of the pipelines which contributes to the increase in the maintenance cost of pipeline directly affecting the cost of fuel. An unmanned powered Parafoil aerial vehicle was developed for monitoring the oil and gas pipeline. It is envisioned that the vehicle would follow a planned trajectory to the target, and infra red camera based system would be employed for extracting details about pipeline leakages, thefts, internal corrosion, internal waxing, etc. In this paper, a 9DOF Parafoil simulation was created in the Matlab/Simulink environment to study the Parafoil dynamics and assess the feasibility of the system. Longitudinal dynamics and direction control has been modeled and studied in detail. Thrust, pitch angle, glide angle and angle of attack was studied for the developed model and is validated with Lingards's model. Nomenclature A,B,C= apparent mass terms A* = canopy aspect ratio b = canopy span d = diameter of a suspension line C D = drag coefficient C L = lift coefficient C Y = side force corfficient C lp ,C lr = rolling moment damping coefficient C mc/4 = pitching moment coefficient at quarter chord C mq = pitching moment damping coefficient C nr ,C np = yawing moment damping coefficients c = canopy chord length F = force g = acceleration due to gravit h,h* = canopy spanwise camber height, and h/c ratio, respectively I = inertia matrix I A ,I B ,I C = apparent inertia terms M = mass matrix l = length of control line pulled m = mass q = dynamic pressure p,q,r = roll, pitch and yaw rates R = link length

“…The controller has a heading tracking function, which receives the target heading angle from the higher level guidance logic and outputs a control signal to reduce the error among measured and target heading 4 . Classical feedback controller is adopted such that the gyroscope output can be used directly.…”

One of the most important issues currently facing the oil and gas industries is the safety and security of pipelines which deliver crude oil from the reservoir to the refineries. Many complications such as waxing, slugging, rusting, theft, etc. obstruct the regular supply of fuel to the refineries. Continuous monitoring of pipelines is a major hurdle because of climatic conditions, length of the pipelines, identification of leakage, etc. Here we showcase an unmanned autonomous powered parachute aerial vehicle designed for monitoring such pipelines, thereby paving a way to solve this problem. The vehicle would follow a planned trajectory for following the pipeline effectively. We present here guidance, navigation and control of a powered parachute aerial vehicle. A nine degree of freedom mathematical model has been presented in detail. Lateral heading and longitudinal altitude hold controller was designed for this purpose. A path planning algorithm verified by actual flight parameters has been designed for following a trajectory using way point navigation.
