Claim:
1. A ventilation system for ventilating a passenger compartment of an aircraft, the ventilation system comprising: a nozzle adapted to be mounted proximate an interior of the aircraft and configured to direct a stream of air into the passenger compartment; a valve spaced apart from the nozzle and positioned upstream of the nozzle, the valve configured to control a flow of air to the nozzle; and a conduit fluidly coupling the valve to the nozzle, the conduit configured to convey the flow of air from the valve to the nozzle, wherein the nozzle includes a transitional section having a first cross-sectional area at an upstream portion of the transitional section and a second cross-sectional area at a downstream portion of the transitional section and wherein the first cross-sectional area is greater than the second cross-sectional area, wherein the nozzle includes a pintle disposed in the transitional section, and wherein the transitional section comprises a pathway surface and the pintle comprises a pintle surface, and wherein a segment of the pathway surface is substantially equidistant from a corresponding segment of the pintle surface, wherein the pintle is attached to the nozzle via a plurality of tabs and wherein each tab of the plurality of tabs extends through a pathway formed by the pathway surface of the transitional section and the pintle surface of the pintle and wherein each tab is at least partially configured as an airfoil.
