There are numerous problems with the ramjet engine, however.

His wings were swept back, and four ramjet engines depended from them.

These missiles travel faster than the speed of sound, usually using ramjet engines.

After it was withdrawn from service, several were used for various test programs, including one evaluating ramjet engines.

However, she can also fly within an atmosphere, making use of an aerodynamic design and ramjet engines.

With its four ramjet engines, it has a range of 130 km and a speed greater than Mach 2.5.

Therefore ramjet engines are limited to approximately Mach 5.

He also pioneered research on large-scale ramjet engines.

This variant has been test-fired and uses a solid-fuel ramjet engine.

Ramjet engines differ in many ways from traditional gas turbine engines, but most of the same principles hold.

"Big stovepipes, ramjet engines, they can come in on a ballistic track at about twenty-two hundred miles per hour.

Turbulators can also be put to use in certain internal combustion engines - particularly, a ramjet engine.

Fuel economy, or thrust specific fuel consumption in aircraft terms, of ramjet engines is extremely poor.

II with a longer range (around 75 miles) achieved with improved ramjet engine and larger boosters.

A key trait of ramjet engines is that combustion is done at subsonic speeds.

Instead, it has a biological version of a ramjet engine - complete with a turbine of bone and gristle.

An electric field can electrostatically attract the positive ions, and thus draw them inside a ramjet engine.

His group invented the propulsion system for Talos, the first surface-to-air missile to use a ramjet engine.

Once over the ocean the missiles would gradually step-climb to twenty thousand feet, where their ramjet engines would be more efficient.

The ramjet engine consists mostly of a large tube, and is relatively easy to air-cool by forcing air around the engine.

Propulsion: two side-mounted ramjet engines at the rear of the airframe with 4 rocket boosters.

The scooped ions will however have an electric field-induced velocity when they are drawn inside of the ion ramjet engine.

Project Pluto was a United States government program to develop nuclear powered ramjet engines for use in cruise missiles.

Although ramjet engines are simpler in design as they have virtually no moving parts, they are incapable of operating at low flight speeds.

Testbed for two underwing ramjet engines.
