In recent years, an unprecedented interest in novel and revolutionary space missions has risen out of the advanced NASA and ESA programs. Astrophysicists, astronomers, space systems engineers, mathematicians and scientists have been cooperating to implement novel and ground-breaking space missions. Recent progress in mathematical dynamics has enabled development of specialised spacecraft orbits and propulsion systems. Recently, the concept of flying spacecraft in formation has gained a lot of interest within the community. These progresses constitute the background to a significant...

Experience firsthand the joys of building and flying your very own model airplane design. Put into practice the lessons from my previous book, RCadvisors Model Airplane Design Made Easy. Follow along as we design, build, and fly a modern radio-controlled model airplane.

Lofty Design Goals

Incorporating the latest innovations and research results, the design looks deceptively simple. However, 20 prototypes had to be built before one finally met all the design goals:

• Build it in just one day for less than $5.
  
• A joy to fly with no bad...

Whirl flutter is the aeroelastic phenomenon caused by the coupling of aircraft propeller aerodynamic forces and the gyroscopic forces of the rotating masses (propeller, gas turbine engine rotor). It may occur on the turboprop, tilt-prop-rotor or rotorcraft aircraft structures. Whirl Flutter of Turboprop Aircraft Structures explores the whirl flutter phenomenon, including theoretical and practical as well as analytical and experimental aspects of the matter. The first introductory part gives a general overview regarding aeroelasticity, followed by the physical principle and the...

Liquid Acquisition Devices for Advanced In-Space Cryogenic Propulsion Systems discusses the importance of reliable cryogenic systems, a pivotal part of everything from engine propulsion to fuel deposits. As some of the most efficient systems involve advanced cryogenic fluid management systems that present challenging issues, the book tackles issues such as the difficulty in obtaining data, the lack of quality data and models, and the complexity in trying to model these systems.

The book presents models and experimental data based on rare and hard-to-obtain cryogenic data. Through...
