你问的这个三角形的东西应该是下图，大翼根部下方的三角形，还是凹进去的

看看局部的图

其实这个就是冲压进气口，看看手册描述吧

These are the two sets of ram air ducts for each pack system:

Ram air inlet

Ram air exhaust.

Purpose

The ram air inlet ducts let cooling air flow from the ram air inlet to the heat exchangers. The ram air exhaust ducts let air flow from the heat exchangers discharge overboard.

Location

The ram air inlet ducts are outboard of the air conditioning compartment. They extend forward to the ram air inlet in the wing-to-body fairing.

The ram air exhaust ducts are aft of the air conditioning compartments. You get access to the exhaust ducts from the air conditioning compartment.

Physical Description

There are two ram air inlet ducts, forward and aft. The forward duct is made of fiberglass reinforced polymer, the aft duct is made of kevlar. The forward section of the inlet ducts attach to the airplane structure at the forward part of the ram air inlet. They attach to the aft section with a flex duct and band clamps. There are tie-rods that attach the ducts to the structure at the center connection of the forward and aft ducts. The aft duct has a flange connection to a web on the outboard side of the heat exchangers. An inspection door is in the aft inlet duct at the aft end. The ram air exhaust ducts attach to the aft end of the primary pack air plenum. They attach to the airplane structure at their aft end with a flex duct and band clamps.
