Yakovlev S V Stol Fighters

Beskrivelse af udviklingen og teknologien bag russiske V/STOL jagerfly.

Yakovlev Yak-3 is considered one of the best World War 2 fighters, invariably praised by those who flew it in combat for its remarkable performance. The Germans also treated it with respect, which is perhaps best illustrated by Generalleutnant Walter Schwabedissen's remark: The Yak-3 was a tough nut to crack for our pilots. It outperformed our machines in speed, maneuverability and rate of climb. The emergence of Yak-3 was a compromise between the need to improve the Yak-1's characteristics and the limitations of Soviet aircraft industry and its outdated technologies. The basic design concept took those shortcomings into account, which allowed a rapid launch of mass production of this inexpensive fighter. This in turn would provide frontline units with timely deliveries of new equipment to recoup combat losses. The key to Yak-3's success was not the use of a new powerplant (in those days hard to come by in the USSR), but rather squeezing every bit of performance out of the M-105PF engine, which resulted in a five percent increase in power output. In combination with some serious weight shedding, the Yak-3 had a significantly better performance than the Yak-1. At altitudes up to 5,000 m (which is where most of the air combat over Eastern Front took place), Yak-3 outperformed both the Bf-109 and Fw-190 in rate of climb and maneuverability. Unlike the Yak-1, the new fighter could also stay with the enemy in a dive.

For this study, a group of Russian authors were commissioned to describe and assess the arms trade policies and practices of Russia under new domestic and international conditions. The contributors, drawn from the government, industry, and academic communities, offer a wide range of reports on the political, military, economic, and industrial implications of Russian arms transfers, as well as specific case studies of key bilateral arms transfer relationships.

This book provides a comprehensive basics-to-advanced course in an aero-thermal science vital to the design of engines for either type of craft. The text classifies engines powering aircraft and single/multi-stage rockets, and derives performance parameters for both from basic aerodynamics and thermodynamics laws. Each type of engine is analyzed for optimum performance goals, and mission-appropriate engines selection is explained. Fundamentals of Aircraft and Rocket Propulsion provides information about and analyses of: thermodynamic cycles of shaft engines (piston, turboprop, turboshaft and propfan); jet engines (pulsejet, pulse detonation engine, ramjet, scramjet, turbojet and turbofan); chemical and non-chemical rocket engines; conceptual design of modular rocket engines (combustor, nozzle and turbopumps); and conceptual design of different modules of aero-engines in their design and off-design state. Aimed at graduate and final-year undergraduate students, this textbook provides a thorough grounding in the history and classification of both aircraft and rocket engines, important design features of all the engines detailed, and particular consideration of special aircraft such as unmanned aerial and short/vertical takeoff and landing aircraft. End-of-chapter exercises make this a valuable student resource, and the provision of a downloadable solutions manual will be of further benefit for course instructors.

This book offers the first complete account of more than sixty years of international research on In-Flight Simulation and related development of electronic and electro-optic flight control system technologies (“Fly-by-Wire” and “Fly-by-Light”). They have provided a versatile and experimental procedure that is of particular importance for verification, optimization, and evaluation of flying qualities and flight safety of manned or unmanned aircraft systems. Extensive coverage is given in the book to both fundamental information related to flight testing and state-of-the-art advances in the design and implementation of electronic and electro-optic flight control systems, which have made In-Flight Simulation possible. Written by experts, the respective chapters clearly show the interdependence between various aeronautical disciplines and in-flight simulation methods. Taken together, they form a truly multidisciplinary book that addresses the needs of not just flight test engi neers, but also other aeronautical scientists, engineers and project managers and historians as well. Students with a general interest in aeronautics as well as researchers in countries with growing aeronautical ambitions will also find the book useful. The omission of mathematical equations and in-depth theoretical discussions in favor of fresh discussions on innovative experiments, together with the inclusion of anecdotes and fascinating photos, make this book not only an enjoyable read, but also an important incentive to future research. The book, translated from the German by Ravindra Jategaonkar, is an extended and revised English edition of the book Fliegende Simulatoren und Technologieträger , edited by Peter Hamel and published by Appelhans in 2014.
