This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of unmanned aerial vehicles (UAVs) for atmospheric research during the last years undergoes a remarkable growth all over the world due to their several advantages. They are a new tool for profiling the main parameters of the atmospheric boundary layer (ABL) such as temperature, humidity and wind vector, as well as for turbulence observations. Their development was inspired by instrumented airplanes. In addition, they are complementary to other existing platforms such as instrumented towers and airplanes, and radiosondes, since they can fly in areas unreachable by these other platforms. We have developed two instrumentation packages for wind and turbulence observations in the atmospheric boundary layer for two UAVs of distinct sizes. The first one is a small size UAV (3.5 kg payload included and with a wingspan of 2.6 m) called OVLI-TA (Objet Volant Leger Instrumenté-Turbulence Atmosphérique). The second one is the fixed wing UAV called BOREAL which has a larger size (25 kg including a payload of 5 kg and with a wingspan of 4.2 m).The meteorological instrumental package of OVLI-TA is composed of a five-hole probe that replaces the nose of the drone, a Pitot probe to measure static and dynamic pressure, a fast inertial measurement unit, a GPS receiver, as well as temperature and moisture sensors. Moreover, for autonomous flights the Pixhawk autopilot is used. The wind tunnel calibrations of the five-hole probe were conducted in order to determine the calibration coefficients of the angles of attack and sideslip. I present the analysis of a qualification flight test conducted in March 2016 in Lannemezan, in the atmospheric research center (CRA) equipped with an instrumented 60 m tower, as well as of the flights conducted in June and July 2016 during the international project DACCIWA (Dynamics-Aerosol-Chemistry-Clouds Interactions in West Africa), in Benin. This study allows evaluating the capacity and performances of OVLI-TA to measure mean values of wind, temperature and humidity, along with turbulence. In this assessment, observations from the 60 m tower and radiosondes were used as a reference.BOREAL's advantages over OVLI-TA lie in its larger payload capacity, its flight endurance that could reach 9 hours, and also its ability to fly in more adverse weather conditions. The developed instrumentation includes a GPS-IMU platform, a five-hole probe replacing the nose of the UAV which measures the angles of attack and sideslip, a Pitot tube, in addition to temperature and humidity sensors. In order to calibrate the five-hole probe, I analyzed the data of wind tunnel test and I used FLUENT software for computational fluid dynamics (CFD) simulations. Furthermore, the first qualification flight test conducted in 2018 allowed us to determine the optimal airspeed of the UAV at which the vibrations are significantly reduced to an acceptable level. Subsequently, in 2020, a first campaign was carried out in Lannemezan in order to qualify the BOREAL capacities to measure wind and turbulence and this following comparisons with the instrumented tower. The UAV's performances are presented in details.

Download or read book Applications of Small Unmanned Aircraft Systems written by J.B. Sharma and published by CRC Press. This book was released on 2019-10-18 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in high spatial resolution mapping capabilities and the new rules established by the Federal Aviation Administration in the United States for the operation of Small Unmanned Aircraft Systems (sUAS) have provided new opportunities to acquire aerial data at a lower cost and more safely versus other methods. A similar opening of the skies for sUAS applications is being allowed in countries across the world. Also, sUAS can access hazardous or inaccessible areas during disaster events and provide rapid response when needed. Applications of Small Unmanned Aircraft systems: Best Practices and Case Studies is the first book that brings together the best practices of sUAS applied to a broad range of issues in high spatial resolution mapping projects. Very few sUAS pilots have the knowledge of how the collected imagery is processed into value added mapping products that have commercial and/or academic import. Since the field of sUAS applications is just a few years old, this book covers the need for a compendium of case studies to guide the planning, data collection, and most importantly data processing and map error issues, with the range of sensors available to the user community. Written by experienced academics and professionals, this book serves as a guide on how to formulate sUAS based projects, from choice of a sUAS, flight planning for a particular application, sensors and data acquisition, data processing software, mapping software and use of the high spatial resolution maps produced for particular types of geospatial modeling. Features: Focus on sUAS based data acquisition and processing into map products Broad range of case studies by highly experienced academics Practical guidance on sUAS hardware, sensors, and software utilized Compilation of workflow insights from expert professors and professionals Relevant to academia, government, and industry Positional and thematic map accuracy, UAS curriculum development and workflow replicability issues This book would be an excellent text for upper-level undergraduate to graduate level sUAS mapping application courses. It is also invaluable as a reference for educators designing sUAS based curriculum as well as for potential sUAS users to assess the scope of mapping projects that can be done with this technology.

Download or read book Uninhabited Air Vehicles written by National Research Council and published by National Academies Press. This book was released on 2000-06-28 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: U.S. Air Force (USAF) planners have envisioned that uninhabited air vehicles (UAVs), working in concert with inhabited vehicles, will become an integral part of the future force structure. Current plans are based on the premise that UAVs have the potential to augment, or even replace, inhabited aircraft in a variety of missions. However, UAV technologies must be better understood before they will be accepted as an alternative to inhabited aircraft on the battlefield. The U.S. Air Force Office of Scientific Research (AFOSR) requested that the National Research Council, through the National Materials Advisory Board and the Aeronautics and Space Engineering Board, identify long-term research opportunities for supporting the development of technologies for UAVs. The objectives of the study were to identify technological developments that would improve the performance and reliability of "generation-after-next" UAVs at lower cost and to recommend areas of fundamental research in materials, structures, and aeronautical technologies. The study focused on innovations in technology that would "leapfrog" current technology development and would be ready for scaling-up in the post-2010 time frame (i.e., ready for use on aircraft by 2025).

Available in PDF, EPUB and Kindle. Book excerpt: This Phase I study has demonstrated the feasibility of developing a low-cost unmanned air vehicle (UAV) designed for a range of oceanographic research missions, including photogrammetry, radiometry, video imaging, and atmospheric profiling, at altitudes of up to 3 km and a range of 300 km. The work included identification of a data link, control system, autopilot, automated launcher, and recovery parachute. These subsystems will allow straightforward programming of a wide range of mission profiles and instrumentation control and accurate aircraft positioning (including differential GPS positioning within 10 km of a ground station). We also demonstrated a low-cost radio-controlled aircraft capable of carrying a 4-kg instrument payload and an autopilot that minimizes the skill (or control algorithm complexity) required to fly the aircraft. We have estimated that a complete UAV system, including the ground station and all avionics, can be sold commercially for under $35K.

Download or read book Unmanned Aircraft Design written by Mohammad Sadraey and published by Morgan & Claypool Publishers. This book was released on 2017-09-19 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides fundamental principles, design procedures, and design tools for unmanned aerial vehicles (UAVs) with three sections focusing on vehicle design, autopilot design, and ground system design. The design of manned aircraft and the design of UAVs have some similarities and some differences. They include the design process, constraints (e.g., g-load, pressurization), and UAV main components (autopilot, ground station, communication, sensors, and payload). A UAV designer must be aware of the latest UAV developments; current technologies; know lessons learned from past failures; and they should appreciate the breadth of UAV design options. The contribution of unmanned aircraft continues to expand every day and over 20 countries are developing and employing UAVs for both military and scientific purposes. A UAV system is much more than a reusable air vehicle or vehicles. UAVs are air vehicles, they fly like airplanes and operate in an airplane environment. They are designed like air vehicles; they have to meet flight critical air vehicle requirements. A designer needs to know how to integrate complex, multi-disciplinary systems, and to understand the environment, the requirements and the design challenges and this book is an excellent overview of the fundamentals from an engineering perspective. This book is meant to meet the needs of newcomers into the world of UAVs. The materials are intended to provide enough information in each area and illustrate how they all play together to support the design of a complete UAV. Therefore, this book can be used both as a reference for engineers entering the field or as a supplementary text for a UAV design course to provide system-level context for each specialized topic.
