Hypersonic flight is flight through the atmosphere below altitudes of about 90 km (56 mi) at speeds greater than Mach 5, a speed where dissociation of air begins to become significant and high heat loads exist. Speeds over Mach 25 have been achieved below the thermosphere as of 2020. [1]
In December 2014, NASA awarded Lockheed Martin a contract to study the feasibility of building the SR-72's propulsion system using existing turbine engine technologies, The $892,292 (~$1.13 million in 2023) contract funded a design study to determine the viability of a TBCC propulsion system by combining one of several current turbine engines, with a very low Mach ignition Dual Mode Ramjet (DMRJ).
Like many X-series aircraft, the X-15 was designed to be carried aloft and drop launched from under the wing of a B-52 mother ship. Air Force NB-52A, "The High and Mighty One" (serial 52-0003), and NB-52B, "The Challenger" (serial 52-0008, also known as Balls 8) served as carrier planes for all X-15 flights
A Chinese aerospace firm has completed the first test flight of a passenger plane that it claims can fly at Mach 4 – more than twice the speed of Concorde.. Beijing-based Space Transportation ...
The legendary Skunk Works had a hand in developing Tom Cruise’s fastest plane yet. Darkstar, the Hypersonic Jet in ‘Top Gun: Maverick,’ Could Become a Real Plane Skip to main content
Currently the Air Force’s remaining hypersonic project of record is the air-breathing HACM cruise missile, which at least has potential to be more affordable and stealthy than a hypersonic glide ...
Aircraft that can fly at hypersonic speed, ie. between Mach 5 and 25. Subcategories. This category has the following 4 subcategories, out of 4 total. H.
In Hermeus’s hypersonic design, a ramjet, which can only operate at high speeds as it uses this air to pressurize air and fuel in the combustion chamber, kicks in and carries the theoretical ...
