Osprey’s examination of German air forces of World War I (1914-1918). The Imperial German Army Air Service of World War I grew from just 500 men in 1914 to 80,000 in 1918, inventing in the process a wholly new form of warfare. The exploits of the first fighter ‘aces’ have been widely celebrated, and have tended to overshadow the other, equally important branches of the fighting air forces – the reconnaissance and ground attack units, the airships and strategic bombers. This concise but fact-packed guide to both the Army and Naval Air Services – their command, organization, strength, training, support services andoperations – offers a morebalanced picture, while giving the heroes of the Jagdstaffeln their full due. Uniforms and flying clothing are described in detail, and illustrated with rare photographs and meticulous colour plates.

English | 2004 | pages: 66 | ISBN: 1841767107 | PDF | 20,3 mb
Osprey’s study of British air defenses during World War II (1939-1945). German daylight raids on Britain began in the summer of 1940. They were expected and the country had been preparing for quite some time. Searchlights were in place, Fighter Command had been expanded, and anti-aircraft guns were being manufactured. It was from these first preparations that Britain developed tactics to counter the many air raids over the following years. This book shows how Britain prepared for air raids in the run up to the war and details all the tactics that were developed during the war to counter the many aerial attacks. Among the defence systems covered are anti-aircraft guns, barrage balloons and the RADAR system.

Free Download Martin Bowman, Mark Styling, "B-17 Flying Fortress Units of the Eighth Air Force"
English | 2000 | pages: 111 | ISBN: 1841760218 | PDF | 28,2 mb
The Boeing B-17 has come to epitomise the American war effort in Europe during World War II (1939-1945), the huge four-engined heavy day bomber taking the fight to Germany from the late summer of 1942 through to VE-Day. The primary operator of the Flying Fortress in Western Europe was the ‘Mighty Eighth’. This volume, which is the first of two dealing exclusively with the ‘Mighty Eighth’, covers the 15 Bomb Groups of the First Air Division, each of which controlled four squadrons. The evolution of the force is traced through first-hand accounts of those individuals that took part in the action.

Free Download Chris Chant, Mark Rolfe, "Air War in the Gulf 1991"
English | 2001 | pages: 99 | ISBN: 1841762954 | PDF | 8,6 mb
In August 1990 Saddam Hussein’s Iraqi forces invaded and occupied the small Arab state of Kuwait. This book analyses the ensuing Gulf War (16 January – 28 February 1991) – a war fought to expel Iraq and restore Kuwaiti independence if not, as one British MP tartly observed, to defend democracy. The allies under General Schwarzkopf launched five weeks of air attacks, deploying 1,800 technologically highly advanced aircraft from the US, British, French and Saudi air forces. Many of these machines, including the British Tornadoes and US F-117A Stealth fighters, had never before engaged in combat, and their combined assault, watched by millions on TV, combined impressive accuracy with firepower to which the Iraqi forces had no answer.

Free Download Heating and Cooling of Air Through Coils: Principles and Applications
by Yongjian Gu
English | 2023 | ISBN: 1032266635 | 289 pages | True PDF | 18.25 MB
Heating and Cooling of Air Through Coils combines theory and practice to cover the fundamentals in the processes of heating and cooling of air through coils and the key aspects in the psychrometric chart, the coil fluid piping systems, the coils, and the energy sources for the fluid in the coils. This book covers the integral elements that have a significant impact on the heating and cooling of air through coils, including the coil types, coil tube constructions and arrangements, and fluid flow characteristics in the coils. It also discusses sustainable and renewable energy sources used to heat and cool the fluid flowing in the piping system and the coils. In addition, the book covers the application of coils in central air-conditioning systems and split air-conditioning systems. This book will interest engineers and researchers involved in the design and operation of heat exchangers and HVAC systems. It can also be used as a textbook for undergraduate and graduate students majoring in relevant fields, such as thermal and fluids HVAC, and energy management.
