In addition to the static flame traps, mobile units were created.
2.
Levers in many of the levels can be pulled to switch flame traps on and off.
3.
A static flame trap was prepared with perforated pipes running down the side of a road connected to a elevated tank.
4.
A mobile flame trap comprised surplus bulk storage tanks on trucks, the contents of which could be hosed into a sunken road and ignited.
5.
A static flame trap allowed a length of road, typically, to be covered in flame and smoke at a moment's notice.
6.
Within three weeks the village bristled with defences including fifteen casemates and a variety of flame traps, flame fougasses and other anti-tank devices.
7.
Many of the first ideas to be tried proved fruitless, but experience quickly led to the development of the first practical weapon : the static flame trap.
8.
Because there was a shortage of pumps they were badly needed for fighting fires started by bombing a simpler type of mobile flame trap was also designed.
9.
No intercooler, aftercooler, or backfire screen ( flame trap ) were incorporated into these two-stage V-1710 engines ( except for the V-1710-119 used on the experimental P-51J, which had an aftercooler ).
10.
In high-powered supercharged aircraft piston engines such as the Rolls-Royce Merlin and Griffon, backfiring into the inlet manifold is prevented with flame traps inside the manifold, the traps preventing the flame propagating into the compressed air / fuel mixture within the manifold.
