SUBSONIC

Subsonic speed refers to any speed below the speed of sound, which is approximately 767 miles per hour (1,235 kilometers per hour) at sea level under standard atmospheric conditions. Anything moving slower than the speed of sound is considered subsonic. In aviation, this means aircraft are flying at speeds slower than Mach 1. 

Key points about subsonic speed:

Definition:

Subsonic speed is any speed less than the speed of sound. 

Speed of Sound:

The speed of sound varies slightly with temperature and altitude, but it's generally around 767 mph (1,235 km/h) at sea level. 

Mach Number:

The Mach number is the ratio of an object's speed to the speed of sound. Subsonic speed is defined as a Mach number less than 1 (M < 1). 

Aviation:

Most commercial, private, and military aircraft operate at subsonic speeds, which is a crucial segment of aviation where aerodynamic efficiency and noise reduction are important. 

Subsonic Ammunition:

In the context of firearms, subsonic ammunition refers to bullets that travel below the speed of sound, avoiding the "crack" associated with supersonic bullets. 

SUPERSONIC

Supersonic refers to anything moving faster than the speed of sound. In aviation, this translates to aircraft flying at speeds greater than Mach 1 (the speed of sound). Specifically, supersonic flight typically means speeds between Mach 1 and Mach 5, while speeds exceeding Mach 5 are often classified as hypersonic. 

Here's a more detailed explanation:

Supersonic Speed: This is the speed at which an object moves faster than the speed of sound, which is approximately 768 mph in dry air at sea level. 

Mach Number: The speed of an aircraft is often expressed as a Mach number, which is the ratio of the aircraft's speed to the speed of sound. 

Supersonic Flight: Any flight that is faster than Mach 1 is considered supersonic. 

Hypersonic Flight: Speeds greater than Mach 5 are typically referred to as hypersonic. 

Transonic Flight: This refers to the speeds around Mach 1, where parts of the air surrounding an object can reach supersonic speeds, like the ends of rotor blades. 

Sonic Boom: When an object flies faster than the speed of sound, it creates a shockwave called a sonic boom. 

Supersonic Aircraft: Aircraft designed to achieve and sustain supersonic flight speeds, such as fighter jets. 

Supersonic Transport: The term for passenger aircraft that can fly at supersonic speeds, like the Concorde and the Tu-144. 

HYPERSONIC 

Hypersonic Speed

In aerodynamics, a hypersonic speed is one that exceeds five times the speed of sound, often stated as starting at speeds of Mach 5 and above

For aircraft speeds which are much greater than the speed of sound, the aircraft is said to be hypersonic. Typical speeds for hypersonic aircraft are greater than 3000 mph and Mach number M greater than five, M > 5. We are going to define a high hypersonic regime at M > 10 to account for re-entry aerodynamics

Supersonic 1.2–5.0 Mach

Hypersonic 5.0–10.0 Mach

High-hypersonic 10.0–25.0 Mach

BREATHING AIR + HUMAN MAXIMUMS

7,000 mph

The air-breathing jet, which obtained its oxygen from the atmosphere, reached Mach 9.6, or nearly 7,000 mph.

Like other ejector seats, the pods had parachutes that would automatically deploy and a built-in survival kit to keep everyone going until a rescue mission could be mounted. If you simply ejected at Mach 10 using a regular jet's ejection system, or even a pressure suit, you would not survive.

It is also far from impossible for any human being to survive a pilot ejection at that speed

The answer is, resoundingly, no. Humans aren't built to withstand the pressure of acceleration to reach Mach 10

HELIS

Helicopters

C/M will use only 8-16 prop speed drones achieving 0-500 km/h speeds safely with back up options to void crash potential

The Westland Lynx holds the official helicopter speed record at 249.09 mph (400.87 km/h). The Eurocopter X3 achieved an unofficial record of 255 knots (293 mph; 472 km/h) in 2013. Some sources also consider the Sikorsky X2 to be a fast helicopter. 

Here's a more detailed look:

Westland Lynx:

This helicopter achieved the official helicopter speed record on August 11, 1986, according to Helicopter Express. The record was recognized by the Fédération Aéronautique Internationale (FAI). 

Eurocopter X3:

This experimental helicopter, developed by Airbus Helicopters, achieved an unofficial record in 2013. It is described as a technology demonstration platform for "high-speed, long-range hybrid helicopter". 

Sikorsky X2:

While not officially holding the record, the Sikorsky X2 is often mentioned in discussions about the fastest helicopters, notes a post on Facebook. It is a highly advanced experimental helicopter designed for speed.
