1. Wind Tunnel Testing on a Generic Model of a Hybrid Lifting Hull
ABSTRACT In this research, an experimental investigation was carried out at the International Islamic University Malaysia - Low Speed Wind Tunnel facility on a generic model of a hybrid lifting hull. Based on the historical trends of non-rigid airships, the fineness ratio of the said hull has been selected equal to 4. Free stream velocity was kept at 20 m/s

2. High-Altitude Platforms — Present Situation and Technology Trends
ABSTRACT High-altitude platforms (HAPs) are aircraft, usually unmanned airships or airplanes positioned above 20 km, in the stratosphere, in order to compose a telecommunications network or perform remote sensing. In the 1990 and 2000 decades, several projects were launched, but very few had continued. In 2014, 2 major Internet companies (Google and Facebook

3. Design, Fabrication and Flight Demonstration of a Remotely Controlled Airship for Snow Scientists
ABSTRACT: A remotely controlled airship was designed, fabricated and demonstrated within a tight timespan of under a month after receiving the go-ahead. The main design requirement for this airship was to be able to operate from a Helipad located at an altitude of 6,572 feet AMSL under ISA+20 deg.C. The images of the terrain below were recorded during the fl

4. Santos Dumont e o desenvolvimento da dirigibilidade de balões
Alberto Santos Dumont (1873-1932) é muito conhecido, no Brasil e na França, por seus trabalhos pioneiros sobre aviação, mas também desenvolveu, antes disso, a técnica de vôo em balões, obtendo importantes resultados na dirigibilidade com aparelhos dotados de motor. Este trabalho analisa sua contribuição neste campo. Esta dissertação apresenta pri

5. Desenvolvimento da infra-estrutura embarcada do projeto AURORA
Unmanned semi-autonomous aerial vehicles present a great and unexplored potential in aerial inspection and research, collecting data &om the environment. Such vehicles allow the user to define the region that must be monitored, data spatial and temporal resolution in which the data must be acquired, and the most adequate type of sensor for each kind of mlSSl
