At Naval Warfare Center Weapons Division (NAWCWD) in China Lake, California, engineers used a 3-D printer to make an inlet for the solid-fuel ramjet engine
they are developing.
It will have a turbofan or turbojet engine as well as a ramjet engine
that will allow the plane to horizontally takeoff from the runway and fly through the atmosphere.
As the name implies, the ramjet engine
rams through the air to compress the fluid and it has no moving parts.
18) At one time, we considered putting a ramjet engine
on the AMRAAM to boost its range and capabilities, as is being done on several next-generation missiles such as the British Meteor, reportedly on the Chinese PL-21, and possibly a version of the Russian R-77/AA-12.
The fourth and final vehicle in question has already been built by airframe contractor Boeing and ramjet engine
developer Pratt & Whitney Rocketdyne.
In the late 1950s and early 1960s, the Pluto facility was used to develop the world's first nuclear-powered ramjet engine
for nuclearpropelled, low-altitude missiles.
According to a report by ABC News, the design stems from the goal of the program - to demonstrate an air-breathing, hypersonic, combustion ramjet engine
, known as a scramjet.
This launch, which took place on August 16, 2002, was the first hesitant step in developing a hypersonic ramjet engine
, an event that even now is only barely beginning to reach the public consciousness.
It is propelled by a ramjet engine
running on liquid fuel, with launch assisted by a solid-rocket booster.
After receiving his MEng in mechanical engineering from McGill University in 195Z Greenwood worked on ramjet engine
development at the Engine Division of the Bristol Aeroplane Company.
Navy took the first step to reintroducing to the an old-but-much-needed technology when it successfully tested a solid-fuel ramjet engine
at Naval Air Warfare Center Weapons Division (NAWCWD) in China Lake, California.
