The Forgotten Speed King: The Story of the Convair 990

✈️ Before Concorde Took the Skies, There Was Convair 990

The world of aviation has always been defined by record-breaking feats and engineering marvels. Before the Concorde became the symbol of high-speed travel, another aircraft aimed to redefine what it meant to fly fast. This wasn’t a supersonic jet that spanned continents in hours. Instead, it was a subsonic wonder: the Convair 990. Engineering innovations allowed this jet to cruise faster than any other airliner before it, and even today, its speed records stand unchallenged. Yet, while the Convair 990 was a marvel of speed, it represented a colossal financial failure for Convair, who lost nearly half a billion dollars on the idea that speed would dominate the commercial airliner market.

🔄 A Brief Glance at the Golden Age of Air Travel

The late 1950s and early 1960s were the golden age of air travel, a period characterized by speed, luxury, and sky lounges. Imagine flying in an era when timing, comfort, and a cocktail at 30,000 feet defined the essence of air travel. In 1958, during this glamorous period, American Airlines decided to push the envelope further. They reached out to aircraft manufacturers with a unique demand: build a jet that could cross the continental United States 45 minutes faster than existing airliners.

  • Boeing’s Stance: Boeing refused outright. According to their engineers, subsonic jets like the Boeing 707 were already maximizing their potential speed while maintaining reasonable range and efficiency.
  • The Convair Response: Unlike Boeing, Convair accepted the challenge. They promised to create an airliner that could cruise at 635 miles per hour and even backed it up with a speed guarantee, risking millions in penalties if they couldn’t deliver on their promise.
  • 🚀 The Making of a Speed Demon: The Birth of Convair 880

    To understand the motivation behind Convair’s ambitious project, you must understand the competitive landscape. The two giants of the time, Boeing and Douglas, had dominated the market with their 707 and DC-8 models, respectively.

  • The Boeing 707 and Douglas DC-8 were revolutionary aircraft that practically transformed air travel from an elite niche into a mainstream method of transportation.
  • Convair’s Challenge: Convair had also ventured into the jetliner market with their model, the Convair 880. However, selling these jets proved to be a herculean task. While Boeing and Douglas secured hundreds of orders, Convair struggled to sell even a few dozen 880s.
  • In this fiercely competitive environment, realizing the market for long-distance jets was already captured, Convair gambled on a different strategy. They bet on speed and luxury, hoping to carve a niche market.

    🏅 Setting Records but Missing Markets: The Convair 880’s Performance

    Convair’s bet wasn’t entirely off-target. During its delivery flight, Delta’s first Convair 880 set an ocean-to-ocean transcontinental record with an average speed of 665 miles per hour, making it the speed champion of subsonic jets at that time.

    However, the market for faster, luxurious jets turned out to be extraordinarily small. Even before the first 880 rolled off the assembly line, it was painfully clear that the new jet wasn’t destined to be a commercial hit. Amidst this struggle, American Airlines’ request for a faster jet seemed like a golden opportunity. Convair decided to take their 880 and modify it into a larger, even faster jet—the Convair 990.

    💪 Engineering Challenges of the Convair 990

    The Convair 990 wasn’t just a Mad Men-era pipe dream. It faced real, daunting engineering challenges that required innovative solutions.

  • Engine Modifications: The Convair 990 required more powerful engines. To achieve this, the turbojets on the 880 were modified to include a separate fan system, creating the world’s first turbofan-powered airliner, boasting 40% more power.
  • Reducing Drag: To counter the transonic drag, the engineers designed new wings with a 39-degree sweep and added large anti-shock bodies to the trailing edges of the wings. These innovations not only reduced drag but also provided additional fuel storage to increase the aircraft’s range.
  • On paper, the Convair 990 seemed to defy the odds. Wind tunnel tests were promising, and the specifications were truly groundbreaking. But as the history of aviation often reveals, the skies are an unforgiving realm.

    🌐 First Flight and Troubles of the Convair 990

    In January 1961, the Convair 990 took to the skies for its maiden flight, and that’s when the problems began to surface.

  • The aircraft couldn’t cruise at the promised 635 miles per hour. Turbulence around the inboard engines complicated the control of the aircraft’s elevators, while the anti-shock bodies caused oscillations in the outboard engines when filled with fuel.
  • Excessive drag areas were discovered all around the aircraft: near the thrust reversers, on the underside of the wing leading edges, and where the wing joined the fuselage.
  • Convair’s engineers enlisted industry experts for help, but despite all efforts and refinements, the 990 failed to meet its speed and range guarantees.

    📉 Negotiations and Reduced Orders: The Struggle Continues

    By the fall of 1961, American Airlines, desperate for new jets, called Convair back to the negotiating table. They drastically reduced their order, asking for only 15 jets—5 of which still needed to be the faster versions. The speed guarantee was also lowered to 620 miles per hour. Despite the continued setbacks, Convair’s engineers didn’t give up. Through persistent effort and countless hours of modification, they eventually succeeded in meeting the new speed guarantee.

  • Another first: The faster Convair 990A managed to hit the 620 mph mark, making it the fastest subsonic airliner ever built. Yet, this achievement proved to be a hollow victory.
  • Market Landscape: By the time the Convair 990 finally took to the skies, the market landscape had drastically changed. Boeing and Douglas dominated the airliner market, leaving little room for Convair’s faster but less practical jets.
  • 🎭 Legacy and Demise: The End of Convair Jetliners

    Convair’s airliners with their added speed and luxury came at the cost of practicality, range, and efficiency—traits the market valued more. The Convair 880 and 990 couldn’t secure enough orders to make them commercially viable. Reportedly, Convair lost half a billion dollars on their jetliner venture, and they never built another airliner again.

    However, the Convair 990 earned a legendary status for several reasons.

  • Rarity: Being rare and not around for long added an aura of mystique around the aircraft.
  • Historical Significance: The Convair 990 was among the last symbols of an era when the aviation industry flirted with speed and luxury without the shackles of today’s economic practicality.
  • ⛽ Fuel Crisis and the Final Blow

    The early 1970s brought a new challenge: the fuel crisis. Most airlines couldn’t wait to offload their fuel-thirsty Convairs, further accelerating the aircraft’s demise. The extra speed these jets provided was no longer attractive when airlines were more concerned with efficiency and operating costs.

    The Convair 990 represented the final throes of another era: a time when the idea of burning an extra 10,000 pounds of jet fuel to save 45 minutes seemed appealing. With the world’s focus shifting towards fuel efficiency and capacity, the era of speed-for-the-sake-of-speed in subsonic jets faded away.

    🔗 Conclusion: The Convair 990’s Place in Aviation History

    In the grand tapestry of aviation history, the Convair 990 stands as a testament to a time when innovation was pursued with relentless ambition, even if it led to financial failure. This aircraft attempted to stretch the limits of subsonic travel, pioneering technologies that would be utilized in future generations of aircraft.

    While the commercial failure overshadowed its engineering achievements, the Convair 990 remains a fascinating chapter in the story of human ingenuity. It reminds us of a daring period in aviation—a time defined by aspirational goals and the quest for speed.
