- Air Budjet: a VTOL virtual operator company in PortugalPublication . Duarte, Manuel Mendes; Baltazar, Maria Emilia; Silva, J.Creation of sustainable transportation service for a new and virtual airline company that uses VTOL aircraft in order to increase mobility and flexibility in Portugal. This study started with the VTOL concepts, peripherally and accessibility, and business models and plans reviews. The air service characterization was then carried out using localization and trajectory optimization algorithms, thus allowing to elaborate two applications (software): one for clients to book their flights and another that compiles flight's data booked by clients and optimizes flights routes/trajectories. With this study, it is possible to depict the viability of the economic-financial results of the new virtual company and the application development results with the optimized trajectories. The development of this air service will increase accessibility and mobility in all regions of Portugal and companies that cannot afford the costs of executive aviation, too. In order to facilitate the booking of the flights, an application was created for the client in order to optimize the company costs related to this air service, and thus to make the cost of a trip more appealing; a second application was elaborated that optimizes the trajectories of the aircraft.
- Air budJets: A VTOL virtual operator company in PortugalPublication . Duarte, Manuel Mendes; Silva, Jorge Miguel dos ReisThe aeronautical industry is evolving very rapidly mainly due to the development of technology. These technological advances have allowed the Man to develop projects that are very ambitious as is the case of "flying cars". This concept has been developed since the '80s, but only now have arisen prototypes capable of satisfying this dream. With this, the appearance of VTOL aircraft, aircraft capable of taking off and landing vertically, without needing any runways to do so. For this project, helicopters are not considered as VTOL aircraft because they are not very energy efficient. Many companies have developed VTOL aircraft, with design and consequently characteristics very different from each other, but having in common being hybrid or fully electric aircraft. For this study, a "fictitious" airline company was created using VTOL aircraft. The service characterization was then carried out, where using localization algorithms and trajectory optimization, we were able to elaborate an application (software) that treats the data of the flights to the marked ones by clients to optimize the routes/trajectories of the flights. Then the elaboration of a model and a business plan was made, and it is possible to observe the viability of the economic-financial results of the new (fictitious) company.
