Simplified UAV Design for Students
Every year, hundreds of students participate in UAV design competitions such as AIAA Design Build Fly or SAE Aero Design: Each team has less than one school year to design, build, and fly an airplane, ranging from a small remote-control airplane to a large autonomous vehicle capable of flying itself and of dropping packages (or even smaller airplanes) that land on a target.
For students without an aeronautical engineering background, who are majoring in fields like mechanical engineering or computer science, many questions naturally arise, such as:
• What wing area is necessary for good flight characteristics?
• How are the optimal aspect ratio and wingspan determined?
• What is a realistic weight goal for an aircraft of this size and engine power?
• How is the best airfoil selected?
• What is the ideal length for the tail cone / tail boom(s)?
• How are the sizes of the tail fins and control surfaces calculated?
• Fewer ribs require a thicker spar, so… What rib spacing will lead to the minimal total structural weight of the wings?
• How can a wing spar be designed that has the required strength and stiffness as well as minimal weight, while also allowing the wing to be easily disassembled into multiple sections for transportability?
• What electronic components are typically found in an RC airplane? How do they work? How can their required capabilities for my airplane (e.g. power and torque) be calculated?
I have mentored multiple groups of students. This book collects my answers to these questions, mostly consisting of step-by-step analyses that use methods and best-practices from the aeronautical industry, from engineering textbooks, and from the expertise of RC airplane builders and ultralight designers.
This book is also a great resource for any hobbyist who wants to design and build an RC airplane while doing at least a little bit of engineering beyond “That looks about right” or “I’ll just copy the way it’s done in similar airplanes”. The simplified analyses in this book can be done by anyone with an understanding of high-school physics and will allow for an airplane that has minimal weight and minimal drag while being able to perform a desired mission (i.e. carrying a desired payload at a desired speed, and being able to take off and land on a desired runway length and to climb out at a desired angle).
The same principles apply to designing an airplane that can carry one or more humans… but, for that, I recommend Daniel Raymer’s Simplified Airplane Design for Homebuilders, a terrific book that was my main inspiration for writing Simplified UAV Design for Students. (In other words: Please do not trust your life to a vehicle that was designed using the simplified equations in my book!)

Unmanned Aerial Vehicles: Robotic Air Warfare 1917–2007 (New…
Unmanned aerial vehicles (UAVs) are the most dynamic field of aerospace technology, and potentially the harbingers of new aviation technology and tactics. They have only emerged from the shadows in recent years, but in fact have been in use for decades. After some limited use in World War II, UAVs began to emerge as a substitute for manned reconnaissance aircraft in the 1950s for missions deemed too dangerous to risk an aircrew. Used in significant numbers in the Vietnam War as well as less-heralded missions such as spy flights over China in the 1950s and 1960s, the contemporary UAV began to emerge in the 1980s.
This book examines the development of this unique and mysterious technology, revealing how it has changed combat through the years and speculating on its potential to transform the nature of warfare in the future. Steven J Zaloga examines the pioneering use of UAVs conducted by the Israeli air and the use of UAVs during Operation Desert Storm. Packed with rare, recently declassified photographs and detailed full-color cutaways, this title goes on to investigate the wide deployment of UAVs over Iraq and Afghanistan today, and considers the possible future of the UAV as an actual military weapon.
