Exempel på hur man kan använda RAMJETS i en mening

• Those that burn additional fuel downstream of the rocket are generally known as ramrockets, rocket-ejector, integral rocket/ramjets or ejector ramjets, whilst those that do not include additional burning are known as ducted rockets or shrouded rockets depending on the details of the expander.
• As in ramjets, a scramjet relies on high vehicle speed to compress the incoming air forcefully before combustion (hence ramjet), but whereas a ramjet decelerates the air to subsonic velocities before combustion using shock cones, a scramjet has no shock cone and slows the airflow using shockwaves produced by its ignition source in place of a shock cone.
• On 14 September 1946, one of the ramjets caught fire forcing pilot, "Slick" Goodlin and engineer Charles Fay, to bail out.
• The combustion chamber in gas turbines and jet engines (including ramjets and scramjets) is called the combustor.
• The reheat used cold air combustion techniques, described by Sotheran and which were derived from their experience with ramjets and plenum chamber burning (PCB) in Pegasus front nozzles.
• Aero engines produced by the company included piston engines, turboprops, turboshafts, turbojets, turbofans, auxiliary power units, ramjets and liquid propellant rocket engines.
• A precooled jet engine is a concept that enables jet engines with turbomachinery, as opposed to ramjets, to be used at high speeds.
• Scramjet programs refers to research and testing programs for the development of supersonic combustion ramjets, known as scramjets.
• Turbopumps are very commonly used with rockets, but ramjets and turbojets also have been known to use them.
• Scramjets are an evolution of ramjets that are able to operate at much higher speeds than any other kind of airbreathing engine.
• Probert made notable contributions to many aircraft technologies, including ramjets, scramjets, vertical takeoff for Harrier jump jets, and reheat (afterburners).
