Effect of air density on kite power

Many researchers have analyzed and gave mathematical equations for the motion of the kite. Different mathematical models for the estimation of kite power has been made by Lloyd, Houska, Argatov I. et al., Jerome Marchand, Pauli Rautakorpi et al. between 1980 to 2013. However in their models for estimation of power and maximum power from kite, they have considered density as constant and is equal to the density of air at the sea level (density of air equals to 1.225 Kg/m3). In this paper, effect of air density on kites flying at high altitude was considered and calculations were made for the estimation of maximum power with air density at the sea level and the air density at the flying height of the kite. For this purpose data given by Pauli Rautakorpi et al. has been considered for estimation of maximum power of the kite. Results were compared for each of the five models, density being constant and density varying with height of the kite. All the five models are compared each other for maximum power with actual air density.
