Buoyancy Lift Augmentation

Yuvaraj G*,Veeranjaneyulu K

This paper proposes an idea of lift augmentation for conventional subsonic aircraft at low along with mathematical analysis. This paper mainly addresses certain changes in power plant requirements and performance characteristics of aircraft after implementation of buoyancy lift augmentation technique. There are certain factors which must be considered for practical implementation of it towards an aircraft without degrading its primary performance and mission profile. Those considerations are discussed with respect to total weight or overall weight of the aircraft and vital changes required in design, manufacturing and operation are addressed. This document also formulates a brief overview on changes that would occur in flight aerodynamic characteristics after the supplementation as well as its impact on flight performance parameters.
