A waverider is a type of hypersonic aircraft that takes advantage of compression lift from its own shock wave.
A waverider is a hypersonic aircraft design that improves its supersonic lift-to-drag ratio by using the shock waves being generated by its own flight as a lifting surface, a phenomenon known as compression lift. To date the only manned aircraft to use the technique was the Mach 3 supersonic XB-70 Valkyrie.

The Boeing X-51 Waverider is an unmanned research scramjet experimental aircraft for hypersonic flight at Mach 5 and an altitude of 70,000 feet (21,000 m). The aircraft was designated X-51 in 2005. It completed its first powered hypersonic flight on 26 May 2010. After two unsuccessful test flights, the X-51 completed a flight of over six minutes and reached speeds of over Mach 5 for 210 seconds on 1 May 2013 for the longest duration powered hypersonic flight.
Waverider is a fictional superhero in the DC Comics universe, a time traveler who was merged with the time stream. Waverider was created by Archie Goodwin and Dan Jurgens. The first version of the character, Matthew Ryder, first appeared in Armageddon 2001 #1. A second version of the character is an alternate timeline counterpart and partner of the original, who became Waverider after his superpowered doppelgänger's death during the storyline Zero Hour: Crisis in Time.
Waverider is a fictional character from the Transformers series. He is an Autobot Pretender who turns into a boat.

In fluid dynamics, the Mach number is a dimensionless quantity representing the ratio of flow velocity past a boundary to the local speed of sound.
In aerodynamics, a hypersonic speed is one that greatly exceeds the speed of sound, often stated as starting at speeds of Mach 5 and above.
Supersonic travel is a rate of travel of an object that exceeds the speed of sound (Mach 1). For objects traveling in dry air of a temperature of 20 °C (68 °F) at sea level, this speed is approximately 344 m/s, 1,125 ft/s, 768 mph, 667 knots, or 1,235 km/h. Speeds greater than five times the speed of sound (Mach 5) are often referred to as hypersonic. Flights during which only some parts of the air surrounding an object, such as the ends of rotor blades, reach supersonic speeds are called transonic. This occurs typically somewhere between Mach 0.8 and Mach 1.2.
A scramjet is a variant of a ramjet airbreathing jet engine in which combustion takes place in supersonic airflow. As in ramjets, a scramjet relies on high vehicle speed to compress the incoming air forcefully before combustion, but whereas a ramjet decelerates the air to subsonic velocities before combustion, the airflow in a scramjet is supersonic throughout the entire engine. That allows the scramjet to operate efficiently at extremely high speeds.
The X-43 was an experimental unmanned hypersonic aircraft with multiple planned scale variations meant to test various aspects of hypersonic flight. It was part of the X-plane series and specifically of NASA's Hyper-X program. It set several airspeed records for jet aircraft. The X-43 is the fastest aircraft on record at approximately Mach 9.6.
In aerodynamics, compression lift refers to an aircraft that uses shock waves generated by its own supersonic flight to generate lift. This can lead to dramatic improvements in lift for supersonic/hypersonic aircraft. Clarence Syvertson and Alfred J. Eggers discovered this phenomenon in 1956 as they analyzed abnormalities at the reentry of nuclear warheads.
A supersonic aircraft is an aircraft able to fly faster than the speed of sound. Supersonic aircraft were developed in the second half of the twentieth century and have been used almost entirely for research and military purposes. Only two, Concorde and the Tupolev Tu-144, ever entered service for civil use as airliners. Fighter jets are the most common example of supersonic aircraft.
Armageddon 2001 was a 1991 crossover event storyline published by DC Comics. It ran through a self-titled, two-issue limited series and most of the annuals DC published that year from May through October. After the event, there were two limited series, Armageddon: The Alien Agenda #1-4 and Armageddon: Inferno #1-4.
Scramjet programs refers to research and testing programs for the development of supersonic combustion ramjets, known as scramjets. This list provides a short overview of national and international collaborations, and civilian and military programs. The USA, Russia, India, and China (2014), have succeeded at developing scramjet technologies.
Wallace D. Hayes was a professor of mechanical and aerospace engineering at Princeton University and one of the world's leading theoretical aerodynamicists, whose numerous and fundamental contributions to the theories of supersonic and hypersonic flow and wave motion strongly influenced the design of aircraft at supersonic speeds and missiles at hypersonic speeds. This greatly enhanced the development of supersonic flight and supersonic aircraft design.
Hypersonic flight is flight through the atmosphere below about 90km at speeds above Mach 5, a speed where dissociation of air begins to become significant and high heat loads exist. In such a regime the aerodynamic flow around a flight body is described by similarity parameters such as its Mach number and its Reynolds number.
The Ayaks is a hypersonic waverider aircraft program started in the Soviet Union and currently under development by the Hypersonic Systems Research Institute (HSRI) of Leninets Holding Company in Saint Petersburg, Russia.
LoFlyte is a supersonic / hypersonic unmanned technology demonstrator stealth aircraft, designed in a joint effort between the US Air Force and NASA to test the characteristics of hypersonic vehicles at low speeds and low altitudes. It first flew in 1996. Built by Accurate Automation.
The 14-X is a Brazilian hypersonic aircraft, named in tribute to the 14-bis of Alberto Santos-Dumont. This aircraft is equipped with a scramjet engine, which is integrated into the fuselage and has no moving parts. The operating principle is that, during flight, the air is compressed by the geometry and speed of the vehicle and directed to the engine at the bottom of the aircraft. Hydrogen is used as the fuel. The vehicle will utilize the “Waverider” concept. A friction wave in the inferior part of the aircraft will give it sustainability.
The Boeing Small Launch Vehicle, or SLV, is an air-launched three-stage-to-orbit launch vehicle concept aimed to launch small payloads of 100 pounds (45 kg) into low-Earth orbit. The program is proposed to drive down launch costs for small satellites as low as US$300,000 per launch ($7,000/kg) and could be fielded by 2020.
The 3M22 Zircon also spelled as 3M22 Tsirkon is a scramjet powered maneuvering anti-ship hypersonic cruise missile developed by Russia.
