The growing interest in development of UAV has created a need for the comparative analysis of performance parameters of different aerofoils. Using this concept different characteristics of aerofoils are explored to design the wing of various UAV fulfilling various purposes. In this research work, the requirements of our desired UAV are established. These requirements are translated into performance parameters. Then the aerofoil that best meet the requirements was optimized from different arbitrary aerofoils through experimental investigation of the performance parameters.
The aim of this research is to assess feasibility of technology demonstration in developing digital resolution direction finding integrating with theta-theta position fixing method. The proposal is to build an integrated architecture which will simultaneously provide both position and direction of an aircraft in even most adverse situations. Theta-theta is one of the methods of positioning an aircraft in flight. Without the help of 'range' information this method uses only the angles generated from two different VOR transmitters to aircraft; it is possible to find the exact location of the aircraft whereas in proposed digital radio direction finding (DRDF), it is possible to find out aircrafts' direction with respect to runway by simulating the codes containing 'bearing' information generated from VOR transmitters. This integrated architecture will reduce the complexity and cost associated with aviation industry.
Integrated avionics architecture is desirable for the next generation aircraft. In this regard we have proposed a data bus network for small aircrafts to meet the demand of bandwidth, data transmission rate, immunity to electromagnetic interference, weight and size. In this paper a brief overview is given on present data bus protocols and a comparison is shown between them. Along with this, this paper compares between copper co-axial cables and optical fiber and proposes a data bus network for small aircrafts, its word format, data generation processes and reasons behind choosing such a network are also discussed. It also calculates different technical specifications and related findings through commercially available software, MATLAB to show the optical fiber based network as a reliable and modular system for use in aircrafts.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
