But a
ramjet motor allows the missile to keep going for well over a minute.
The scramjet, or supersonic combustion
ramjet, is the key technology for air-breathing hypersonic flight at high Mach numbers.
Part I discusses the history, classifications, and performance of air- breathing engines, from Leonardo da Vinci to the 20th century, then discusses different engine types including pulsejet,
ramjet, single- and multi-spool turbojet, and turbofan in both subsonic and supersonic applications.
Alliant Techsystems tests hypersonic engine Thermally throated
ramjet targeted at two near-term projects led by US Air Force Alliant Techsystems (ATK) has demonstrated a simplified hypersonic engine that could enable near-term development of a high-speed strike weapon.
Like former principal procurator fiscal Stuart MacFarlane - Roger
Ramjet to his pals - who feels a shred of pity for his predicament?
A scramjet is a
ramjet that has supersonic combustion.
The company touts its Sweed/
Ramjet alligator shears as "simple to operate and easy to maintain, utilizing two adjustable blades which are designed to he reground to sustain their sharpness."
Reportedly the new missile is powered by a solid-fuel
ramjet engine, giving the missile supersonic speed and increased range, the latter characteristic commonly put at 120-180 km.
The missiles' "air breathing"
ramjet motors enable longer flights and better manoeuvrability.
The term "scramjet" is used to describe the engine s supersonic combustion
ramjet design, which follows the same principles as a
ramjet engine in which air coming into an engine is compressed as it is forced through a narrow neck on its way to the combustion chamber, but at supersonic speeds.
By the 1930s, Leduc's idea consisted of what he called thermopropulsion, later
ramjet. Using Bernouilli's Law, the device, called for air to be pushed through a cylinder that varied in diameter, and compressed into a combustion chamber hot enough to inflame injected gasoline.
Yet even if the design is shelved, its supersonic
ramjet technology may turn up in another Airbus creation.
