Variable Geometry Cooling System
The way to reduce or eliminate excess cooling drag in cruise is to use a variable-geometry cooling system that can change shape to control the amount of air flowing through the cowling.
Cooling Outlet Design
The design must focus on sufficiently cooling the engine while minimizing drag.
Cooling: Internal Flow
Cooling the engine and its accessories requires a continuous flow of air to come in from outside the airplane to absorb heat from the...
Cooling Inlets, Part 2
As we saw last month, an ideal cooling air inlet system should ingest air from the free stream and bring it to rest or...
Cooling Inlets
The cooling air inlet serves two functions: First, and most important, the inlet must ingest enough air to properly cool the engine and accessories...
Cooling
As we saw in last month’s edition of Wind Tunnel, only about one-third of the energy released by burning the fuel in an internal...
