diffuser
Aviation; Jet engines
Aft structural member of an engine. It receives high velocity air from the centrifugal impeller and decreases velocity and increases air pressure. In the combustor, a diffuser forms a divergent flow ...
diffusion
Aviation; Jet engines
Process by which gases intermingle as the result of their spontaneous movement caused by thermal agitation.
directional references
Aviation; Jet engines
Specific definitions of terms referring to gas turbine engines to identify front and rear, right and left, bottom and top.
divergent exhaust duct
Aviation; Jet engines
Used on helicopter. Device to diffuse the exhaust gases rearward and to eliminate thrust.
drag parasite
Aviation; Jet engines
Drag caused by any member or structure which does not contribute to lift, such as engine cowlings.
drag profile
Aviation; Jet engines
Friction resistance produced by a member moving through the air; in simple terms, the "stickness" of air against the surface of an airfoil.
