In this episode of Engineering Secrets we'll discover the marvels of the Northrop Grumman B-2 Spirit, the world's most expensive aircraft, priced at a staggering $2 billion per unit. Join us as we explore the complex construction program costing over $45 billion and learn why this aircraft is a pinnacle of modern engineering.
In this comprehensive breakdown, we'll delve into the unique design of the B-2 Spirit, revealing why it lacks conventional features like a fuselage and tail stabilizer. Find out the science and secrets behind its remarkable stability despite the absence of these elements, and understand the critical role of split rudders in ensuring flawless flight.
We'll take you through the history of stealth technology, tracing back to the revolutionary concepts proposed by Soviet physicist Pyotr Ufimtsev, and how they influenced the B-2's design to appear as mere insects on advanced radar screens.
