The Cleanest Air Filter Vacuums dirt. Wipes grime. In one action. The Dyson Hard vacuum combines powerful suction and a wet wiping action to clean hard floors thoroughly and efficiently. Its dual suction channels suck up dirt from the front and rear of the cleaner head, while its wet wipe removes grime. All in one action.

Using conventional performance analysis, relying on only the laws of thermodynamics, it is possible to understand how the performance parameters affect the component performance, but it is difficult to directly compare the magnitude of various loss sources. A comprehensive framework has been detailed to analyze aero engine loss sources in one common currency. As the common currency yields a measure of the lost work potential in every component, it is used to relate the component performance to the system performance.

"""! ABSTRACT SOLAR POWER UNMANNED AERIAL VEHICLE: HIGH ALTITUDE LONG ENDURANCE APPLICATIONS (HALE-SPUAV) By Manish R Bhatt This project deals with UAV using solar energy as their only source of energy for more than 24 hours flight. Using solar panels, it collects the energy during the day for immediate use but also store the remaining part for the night flight. The objective is to identify, design and analyze such a reusable solar power unmanned areal vehicle for high altitude long endurance application with successful implementation of higher energy density batteries such as Li-su. A detail analysis has been performed to compare similar airplanes to study their successes and failure. An aircraft with similar wingspan as NASA Helios and remarkably less weight, nearly 1135lb, than it is been design. A weight analysis and power sensitivity analysis were researched, and it was shown that this aircraft would generate 75kw of power that is greater then the power available to fly.

  • Unmanned Aerial Vehicle: Tecnologie E Prospettive Future
    Alma Mater Studiorum · Università di Bologna SCUOLA DI SCIENZE Corso di Laurea Magistrale in Informatica Unmanned Aerial Vehicle: tecnologie e prospettive future Relatore: Presentata da: Luciano Bononi Marcello Allegretti Correlatore: Giampiero Giacomello Sessione II Anno Accademico 2015 - 2016 Quale è la vera vittoria? – Quella su se stessi Prima regola dell’Aikido Abstract Partendo dalla definizione di UAV e UAS, arrivando a quella di drone, nella tesi saranno definiti i termini precedenti, ossia un sistema aereo senza pilota a bordo, la nascita del termine drone e le tendenze attuali. Dopo una precisa classificazione nelle quattro categorie principali (droni per hobbisti, commerciali e militari di me- dia grandezza, militari specifici di grandi dimensioni e stealth da combattimento) saranno descritti gli ambiti di utilizzo: da un lato quello militare e della sicurez- za, dall’altro quello civile e scientifico. I capitoli centrali della tesi saranno il cuore dell’opera: l’architettura dell’UAV sarà descritta analizzando la totalità delle sue componenti, sia hardware che software. Verranno, quindi, analizzati i problemi re- lativi alla sicurezza, focalizzandosi sull’hacking di un UAV, illustrandone le varie tecniche e contromisure (tra cui anche come nascondersi da un drone). Il lavoro della tesi prosegue nei capitoli successivi con un’attenta trattazione della normativa vigente e dell’etica dei droni (nonché del diritto ad uccidere con tali sistemi). Il capitolo relativo alla tecnologia stealth sarà importante per capire le modalità di occultamento, le tendenze attuali e i possibili sviluppi futuri degli UAV militari da combattimento. Il capitolo finale sugli sviluppi futuri esporrà le migliorie tecno- logiche e gli obiettivi degli UAV negli anni a venire, insieme ad eventuali utilizzi sia militari che civili.

  • Analysis of Layout and Justification of Design Parameters of a Demonstration Aircraft Based on Solar Cells
    E3S Web of Conferences 164, 13007 (2020) https://doi.org/10.1051/e3sconf /202016413007 TPACEE-2019 Analysis of layout and justification of design parameters of a demonstration aircraft based on solar cells Volodymyr Isaienko1, Volodymyr Kharchenko1,*, Mykhailo Matiychyk1, and Inessa Lukmanova2 1National Aviation University, Kyiv, Ukraine 2Moscow State University of Civil Engineering, 26 Yaroslavskoye Shosse, Moscow, 109377, Russia Abstract. The development of aviation vehicles on SC (solar cells) requires, in particular, evaluations of the technical decisions made regarding the layout of future developments and obtaining their design parameters. Accordingly, it is important to take into account previous developments in the various aviation engineering fields relevant to new aviation vehicles on the SC. Thanks to a detailed analysis of the flight and performance characteristics of widely known aircraft models on the SC from the 70s of the 20th century to the present, a picture of the distribution of aerodynamic schemes and important design parameters with conclusions regarding their choice is obtained. For aircraft on SC, the corresponding boundaries of their work in height and speed are determined in comparison with long-range aircraft. Also, acceptable values of unit load per unit area and specific power have been obtained that allow aircraft to be lifted on the SC at altitudes of at least 20 ths.m. These altitudes are promising for long- haul aircraft to be operated on to SC for the purpose of performing the functions of an "aerodynamic satellite" or the so-called "pseudosatellite". The design parameters of the "pseudosatellite" demonstrator on the SC with a wingspan of 11m and a starting mass of 16 kg were obtained.
