The RAG is a "Ring Airfoil Grenade", not a ramjet.
A ramjet is a device that uses supersonic inlet compression to
compactify the fuel prepatory to ignition. Because it operates in the
supersonic regime, a plume of dispersing fuel is actually a supersonic
compression (as opposed to a subsonic compression requiring decreasing
cross sectional area) and so provides a high efficiency combustion, and
hence exhaust velocity.
Ramjets require hypersonic speeds before they become efficient,
which a grenade most certainly does not get.
Your RAG flies flat because the airfoil provides lift for the
round, thus changing it's ballistics.
