Broadband telecommunications have become the key factor for economic growths around the world, but rural and hard to reach areas are missing out on the opportunity. To overcome this problem, we propose a pseudo-satellite system where telecommunication devices are carried on a perpetually flying solar aircraft cruising at stratospheric altitude. Our aircraft will combine lighter-than-air technology to augment the lift from the wing. Every major components contributing to the aircraft total weight has been considered, resulting in a range of design solutions. We chose wing span and aspect ratio of 50m and 13 respectively, from which other specifications of the aircraft were fixed to. Our design solution has been validated by power and weight balance analysis. System reliability has been demonstrated by Monte Carlo simulation.

This is an overview topic of inflatable structure for aerospace application. An inflatable structure is a promising choice for a wide r application are inflatable wing, space antenna, solar array, inflatable aeroshell and inflatable aerodynamic decelerators. The advantages of inflatable structure are it offers the potential for compact stowing of lightweight structure. This will efficient packaging, easy to deploy and ultimately lead to reduction in mission cost.Historically, inflatable technology has been introduced as a concept in aerospace application with a patent on flying glider th Over the years, many concepts of inflatable were introduced but only a small number of concepts have progress beyond the stage of design and even fewer manage to be completed and used extensively.

“…It allowed the aircraft to change its orientation in a quasistatic manner and fly at different orientations (horizontal to vertical) relative to its forward speed. 2,3,4 This is an attribute of a thrust vectoring propulsion system that would be very beneficial for navigating and performing work in a 3-D environment. Therefore, it was one of the first approaches considered.…”

There are many challenges for robotics, many of which may be placed in the context of robots acting as a teammate to Soldiers. In general one may see a robotic teammate as an unmanned system that complements a Soldier's capability, may perform some of the duties of a Soldier, or may actually protect the Soldier. There is much research that needs to be performed before robots are physically capable of performing as teammates to Soldiers in dynamic environments where speed matters, and in complex 3-D environments where navigation for today's robots is difficult. This research addresses a fundamental obstacle to addressing this issue, which is how to safely and cost effectively develop theory and controls for a new generation of robots that may operate at operations tempo (OPTEMPO) in dynamic complex 3-D environments. This paper documents design and fabrication of a research platform capable of demonstrating theory and control algorithms developed for highly dynamic robotics systems, which may need to navigate and perform a task in complex 3-D environments. The research platform has been designed to address challenging basic research in the areas of airborne manipulation, transition to and interaction with vertical surfaces, exploration of a constrained space such as urban environments (street level to rooftop), forests, and underground facilities. The platform will allow controls development and validation for a vehicle that's weight is at least partially supported by a propulsion system to perform work on the environment and/or an object within the environment.
