A Definition of Supersonic and Hypersonic

Supersonic:

Supersonic speeds refer to speeds which exceed the speed of sound. Otherwise known as Mach 1 velocity. Sound travels approximately 343 meters/second (1,125 feet/second), covering an approximate 1,236km/hour (768 miles/hour). A supersonic velocity object traveling faster than Mach 1 typically exhibits shockwaves or loud sonic blast.

Hypersonic:

Hypersonic speeds are much greater than sound speeds and typically begin around Mach 5, or five times sound speed – this equates to approximately 6,174 km per hour (3 836 miles per hours) or 1,72 kilometers per second (1.07 mile per second). As hypersonic flights cause air compression around an object to become highly compressed causing aerodynamic and extreme heating challenges for flight; to reach and sustain hypersonic flight requires advanced thermal protection systems as well as scramjet propulsion to reach high speeds and maintain them.

Supersonic

Supersonic speeds refer to air speeds exceeding the speed of sound within their medium; typically this refers to air. At 20 degrees Celsius (68 degree Fahrenheit), sound travels at 343 meters per second (1.125 feet per sec) — equivalent to 1,236 kilometers (768 miles). A supersonic velocity, defined as traveling faster than Mach 1, is defined as travelling at speeds exceeding this threshold.

Supersonic speeds have several key characteristics:

Shockwaves: At supersonic speeds, an object traveling at supersonic speed creates shockwaves as air molecules compress rapidly under its rapidly increasing momentum. These shockwaves can create a sonic boom, a loud and distinctive noise caused by the sudden release of energy when the shockwaves reach the ground or an observer.
Aerodynamic Challenges: Aerodynamic forces and phenomena change significantly when transitioning from subsonic to supersonic speeds. The behavior of airflow around an object becomes more complex, and new challenges arise in terms of stability, control and drag. Designing aerodynamically efficient shapes and control surfaces becomes critical to ensuring safe and stable flight.
Heating Effects: The high-speed air molecules impacting the surfaces of an object traveling at supersonic speeds generate intense heat. This aerodynamic heating can cause significant temperature increases on the vehicle’s leading edges and surfaces, requiring the use of specialized materials and thermal protection systems to manage the heat and prevent structural damage.

Supersonic speed has found applications in various domains, including:

Supersonic Aircraft: Concorde was the world’s iconic supersonic aircraft and operated commercially from 1976 until 2003.

Hypersonic speeds exhibit several distinctive characteristics:

Extreme Aerodynamic Heating: When an object moves through the air at hypersonic speeds, the compression of air molecules generates intense heat. Aerodynamic heating technology can quickly reach temperatures well beyond 1,000deg Celsius (1,800deg Fahrenheit). Managing and dissipating this heat is a critical challenge in hypersonic flight.
High-Speed Airflow: At hypersonic speeds, the behavior of airflow around an object becomes highly complex. Strong shockwaves and regions of highly compressed air create unique aerodynamic forces, such as high drag and increased skin friction. Designing vehicles and structures to withstand and utilize these forces effectively is essential.
Scramjet Propulsion: Scramjet engines are used in hypersonic vehicles for propulsion. These air-breathing high-speed engines breathe air. Scramjets rely on the vehicle’s high-speed airflow to compress and ignite the fuel, eliminating the need for traditional fuel combustion systems like turbojets. This enables higher speeds and more efficient propulsion.
