As an expert in the field of aerodynamics and aerospace engineering, I can provide a detailed explanation regarding the speed required to break the sound barrier. The sound barrier refers to the point at which an object moves through the air at the speed of sound, creating a sonic boom as it does so. This phenomenon occurs because sound travels in the form of pressure waves through the air, and when an object surpasses this speed, it compresses these waves in front of it, leading to a shock wave.
The speed of sound is not a constant value; it varies with temperature, humidity, and altitude. However, for the sake of simplicity and to provide a concrete example, we often use the speed of sound in dry air at 20°C (68°F), which is approximately 343 meters per second (m/s), or about 767 miles per hour (mph), 1234 kilometers per hour (km/h), or 1,125 feet per second (ft/s). This is the speed at which the sound barrier is commonly said to be "broken."
Breaking the sound barrier is a significant achievement in aviation history. It was first done by Chuck Yeager in the Bell X-1 aircraft on October 14, 1947. The achievement marked a new era in aeronautics, as it demonstrated that it was possible for man-made objects to travel at supersonic speeds.
When an object approaches the speed of sound, it encounters a type of aerodynamic resistance known as wave drag. This is caused by the shock wave that forms as the object's speed increases. The shock wave increases the drag on the object, requiring more and more energy to overcome. This is why aircraft designed to fly at supersonic speeds have specific shapes and features to minimize wave drag and reduce the energy required to maintain such high speeds.
The shape of an aircraft, particularly the nose and wings, plays a crucial role in its ability to break the sound barrier. A sharp, pointed nose cone helps to concentrate the shock wave into a smaller area, reducing the overall drag. Additionally, the aircraft's wings are often swept back to delay the onset of wave drag and to handle the increased aerodynamic forces at supersonic speeds.
Moreover, the materials used in the construction of supersonic aircraft are also critical. They must be able to withstand the extreme temperatures and pressures associated with supersonic flight. Advanced alloys and composite materials are often employed to ensure the structural integrity of the aircraft at these high speeds.
Breaking the sound barrier is not just about reaching a specific speed; it involves a complex interplay of aerodynamics, materials science, and engineering. The sonic boom created when an object breaks the sound barrier can be quite loud and is one of the challenges faced in supersonic travel. Efforts are being made to develop quieter supersonic aircraft that can reduce the impact of sonic booms on the environment and communities.
In summary, breaking the sound barrier is a remarkable feat that involves overcoming significant aerodynamic challenges and requires sophisticated engineering solutions. The speed to break the sound barrier in dry air at 20°C is approximately 343 m/s, but achieving and sustaining supersonic flight is a multifaceted endeavor that goes beyond simply reaching this speed.

In dry air at 20 --C (68 --F), the sound barrier is reached when an object moves at a speed of 343 metres per second (about 767 mph, 1234 km/h or 1,125 ft/s).
