The Catesby Tunnel is ostensibly a wind tunnel, but one that works opposite to all others (with one notable exception). Instead of rushing wind over a static model, within the Catesby Tunnel, the air is static, but you can drive a car at up to 160 mph, providing a real-world look at how air flows over the car. But, since opening in 2021, it’s also proven to be so much more than just an aerodynamic testing facility. https://lnkd.in/emHKVW5Q #QubeAutomotive #Automotive #Car #WindTunnel #ProvingGrounds #AutomotiveTesting #Catesby #Aerodynamics #AutomotiveIndustry

The SR-71 Blackbird's Heart: The Powerhouse J58 Engine The Lockheed SR-71 Blackbird, a legendary Cold War spy plane, wasn't just a marvel of aerodynamics; it was powered by a marvel of engineering – the Pratt & Whitney J58 afterburning turbojet engine. These engines were unlike anything before them, enabling the Blackbird to achieve its record-breaking speeds and soar above the grasp of enemy defenses. Let's delve deeper into the secrets of the J58 and understand how it made the SR-71 the ultimate high-altitude reconnaissance platform. Beyond Turbojets: A Dual-Personality Powerplant The J58 wasn't your typical jet engine. At lower speeds, it functioned like a conventional turbojet engine. Air entering the engine was compressed, mixed with fuel, and ignited, generating thrust through hot exhaust gases exiting the rear. But that was just half the story. Ramjet Revelation: Unlocking Mach 3 and Beyond The true magic of the J58 came into play at high speeds. As the SR-71 accelerated towards Mach 3 (over 2,200 mph), the J58 transitioned to a ramjet mode. Imagine a scramjet engine – a simpler design with no moving parts. The J58 ingeniously mimicked this design at supersonic speeds. Variable Geometry Inlet: The J58's inlet cone played a crucial role. At low speeds, it extended forward, scooping in more air for efficient turbojet operation. However, at high speeds, the cone retracted, forming a shockwave that compressed incoming air – essentially acting like a giant supersonic ramjet intake. Bleed-Bypass System: Another key innovation was the J58's complex bleed-bypass system. At low speeds, it diverted excess air around the afterburner, ensuring efficient turbojet operation. But as the SR-71 climbed towards its cruising altitude, the bleed-bypass system diverted more and more air directly to the afterburner, maximizing thrust for high-speed flight. The Result: A Speed Demon Devouring the Sky This ingenious combination of turbojet and ramjet functionality allowed the SR-71 to achieve its record-breaking performance: Mach 3+ Speeds: The J58 engines propelled the Blackbird to speeds exceeding Mach 3.2, allowing it to outrun any potential threat and gather intelligence undetected. High-Altitude Operations: The J58's efficiency at high speeds also enabled the SR-71 to operate at altitudes above 85,000 feet, placing it safely above enemy radar and missile capabilities. Beyond Speed: The Challenges of Pushing the Limits The J58 engines, while revolutionary, presented unique challenges: Fuel Guzzler: Operating at high speeds and extreme altitudes demanded a tremendous amount of fuel. The SR-71's internal fuel tanks were specially designed, but it still required mid-air refueling to complete its missions. Heat is the Enemy: Friction at hypersonic speeds generated immense heat. The J58 engines were constructed with exotic heat-resistant materials and relied on a complex cooling system to prevent meltdowns.
