Learjet 23/24

Welcome to an exploration of the Learjet 23/24, a remarkable contribution to the world of aviation that forever altered private jet travel. Built by Learjet—a brand under Bombardier Aerospace, a company renowned for its luxury private jet models—these aircraft were introduced in the 1960s with an intended use of setting a new standard for private and business aviation.

What makes these aircrafts notable? Simply put, they were revolutionary. The Learjet 23/24 were the first true business jets and defined an entire segment of aviation history. Let's dive in to learn more.

HISTORY: The Making of an Icon

The Learjet 23, the progenitor of the iconic Learjet series, made its first flight on October 7, 1963. The 23 model was produced from 1962 to 1966, with a total of 104 being built during that time. Not to be outdone, the Learjet 24 was introduced in 1966, featuring improved range and other design modifications, and remained in production until 1977. Throughout their production runs, these models set numerous world records for speed and altitude, engraving their names in the annals of aviation history.

DESIGN: Unmistakably Learjet

The Learjet 23/24 are compact, sleek, and streamlined. With a wingspan of 35.7 feet and a length of 43.3 feet, their small stature belies their potent performance. These aircrafts can seat up to 8 passengers (in high-density configuration), with an average configuration accommodating six passengers and two crew members. The design is characterized by its low/straight wing, a T-tail, and two rear-mounted engines—an iconic silhouette that became a standard for future business jets.

PERFORMANCE: Pushing the Boundaries

Blessed with top speeds of up to 561 mph (Mach 0.81) and a maximum cruising altitude of 51,000 feet, the Learjet 23/24 truly brought “sky-high” to a new level. These jets showcased an impressive range of approximately 1,830 miles, providing efficient, high-speed, long-distance travel for business professionals and private users alike. The fuel efficiency of these aircraft was commendable for their era, further cementing their place as pioneering models in the industry.

TECHNOLOGY: Innovating the Sky

The Learjet 23/24 were pioneers in aviation technology. They boasted advanced avionics for their time, including autopilot systems and modern navigational aids. Additionally, their propulsion system set them apart from other aircraft models. The General Electric CJ610 turbojet engines, known for their reliability and performance, powered these jets. The inclusion of thrust reversers—a rarity in small jet aircraft at the time—also contributed to their unique standing.

VARIANTS: More Than One Way to Fly

Several variants of the Learjet 24 model were produced over the years, each designed to cater to specific needs. The Learjet 24B was designed with a higher maximum takeoff weight, while the 24D model incorporated further improvements to range and performance. Later models, such as the 24E and 24F, featured a redesigned wing that improved aerodynamics and efficiency.

OPERATORS: Trusted by the Best

The Learjet 23/24 aircraft have seen usage by both civil and military operators. On the civilian side, these jets have been popular with private individuals and corporations seeking reliable, efficient private air travel. In the military world, entities like NASA and the Argentina Air Force have utilized these jets for their efficiency and performance capabilities.

Conclusion: A True Aviation Pioneer

In essence, the Learjet 23/24 models were not just aircraft; they were game changers. They redefined what private air travel could be, setting benchmarks in design, performance, and technology that influenced a generation of jet manufacturers.
