The trend towards larger power ratings of wind turbines asks for innovations in power generation, which requires lower weight and cost, smaller size, higher efficiency and reliability. Due to high current-carrying capability and no DC losses of superconductors, a superconducting wind generator can have a superior power to weight/volume ratio with high efficiency. The work in the book mainly focuses on the feasibility study and design of a superconducting DC wind generator.

This book gives a step-by-step approach to the design of a cryogenic infrastructure required for superconducting, all-electric aircraft systems which is also partially applicable to liquid hydrogen fueled subsonic and hypersonic aircraft, as well as hybrids. While there is no shortage of publications on hydrogen fueled aircraft, this book puts the past journal literature through a magnifying glass and condenses it into an engineering strategy for the next steps to enable liquid hydrogen storage and distribution in aircraft. Emphasis is placed on tank design, manufacturability, safety features, and minimum tank weight, providing a holistic focus on the logistics of hydrogen management for all major components within the aircraft as well as on future superconducting motor architecture. The intention is to fully exploit the benefits of a liquid hydrogen reservoir without any need for additional cryogenic fluids, with relevance to cooling of various superconducting components e.g., motors and superconducting cables, as well as the heat sinking of power electronics and for fueling the fuel cell stack system. A liquid hydrogen tank hold-time analysis reveals the main governing factors and describes the required efforts for minimizing onboard boil off for aircraft designs with different flight mission duration. This is followed by an outlook showing where cryotankage technology and cryogenic aircraft architecture may move within the next 20 years embedded in a green hydrogen-based economy and how basic research will need to play a major role to help us realizing these future designs by consequently eliminating whitespace within today's technology landscape. This book is also an aircraft engineering resource on composites, hydrogen properties, general aircraft materials and safety.

A design process for HTS DC cables was developed for high current applications. Based on the design process, a 35 kA HTS DC cable demonstrator was developed. The superconducting elements of the demonstrator were manufactured and tested individually at 77 K. Afterwards, the demonstrator cable was assembled and tested at 77 K. The assembled demonstrator successfully reached 35 kA at 77 K and self field conditions.

This work presents three advances to scale SNSPDs from few-pixel devices to large detector arrays: atomic layer deposition for the fabrication of uniform superconducting niobium nitride films of few-nanometer thickness, a frequency-multiplexing scheme to operate multiple detectors with a reduced number of lines, and the integration of SNSPDs with free-form polymer structures to achieve efficient optical coupling onto the active area of the detectors.

This work presents the development and application of high-speed fluorescent thermal imaging for quench analysis in high-temperature superconductors (HTS). Using a fluorescent coating, with a temperature-dependent light emission, temperature changes can be calculated over 2D surfaces. The technique uncovered peculiar transient effects in novel HTS tape architectures and also helped to verify and better understand hot spot development in both insulated and non-insulated, HTS–wound pancake coils.
