The Secret Horsepower Race

Synopsis

The piston engines that powered Second World War fighters, the men who designed them, and the secret intelligence work carried out by both Britain and Germany would determine the outcome of the first global air war.  Advanced jet engines may have been in development but every militarily significant air battle was fought by piston-engined fighters. Whoever designed the most powerful piston engines would win air superiority and with it the ability to dictate the course of the war as a whole. This is the neverbefore- told story of a high-tech race, hidden behind the closed doors of design offices and intelligence agencies, to create the war's best fighter engine. Using the fruits of extensive research in archives around the world together with the previously unpublished memoirs of fighter engine designers, author Calum E. Douglas tells the story of a desperate contest between the world's best engineers - the Secret Horsepower Race.

Summary

Chapter 1: The Race for Speed

Summary:
The chapter introduces the concept of engine tuning and highlights the various factors that influence engine performance. It explains the importance of maximizing engine efficiency and reducing weight while optimizing power output.

Real Example:
Mazda's rotary engine, known for its high power-to-weight ratio, is an example of engine tuning that prioritized performance over simplicity.

Chapter 2: The Power of Thermodynamics

Summary:
The chapter delves into the thermodynamic principles governing engine operation, including the concepts of heat, pressure, and energy transfer. It explains how these principles can be applied to improve engine efficiency and power output.

Real Example:
Toyota's hybrid technology utilizes regenerative braking systems to capture and store energy that would otherwise be lost during braking. This captured energy is then used to power the electric motor, improving overall fuel economy.

Chapter 3: The Art of Aerodynamics

Summary:
The chapter examines the role of aerodynamics in reducing drag and improving vehicle performance. It discusses various design elements, such as streamlining, spoilers, and air dams, that can be optimized to minimize resistance.

Real Example:
Ferrari's 458 Italia features a sleek, aerodynamic design that reduces drag and improves downforce, resulting in improved handling and stability at high speeds.

Chapter 4: The Importance of Lightweighting

Summary:
The chapter emphasizes the significance of reducing vehicle weight as a means of improving performance. It explores various materials and technologies, such as lightweight alloys and composites, that can be used to reduce weight without sacrificing strength.

Real Example:
Tesla's Model S is constructed from a combination of aluminum and carbon fiber, resulting in a significantly lower weight than traditional steel vehicles. This reduction in weight contributes to its impressive acceleration and range.

Chapter 5: The Future of Power

Summary:
The chapter discusses emerging powertrain technologies, such as hybrid, electric, and fuel cell systems. It explores the advantages and challenges of each technology and their potential to revolutionize the automotive industry.

Real Example:
Hyundai's Nexo fuel cell vehicle emits only water vapor as exhaust, demonstrating the potential of alternative power sources to reduce emissions and improve environmental sustainability.
