THE AERIAL NEMESIS OF SUBMARINES (Jun, 1917)
THE AERIAL NEMESIS OF SUBMARINES
HUNTING THE UNDERSEA PIRATES
This remarkable photograph depicts clearly the type of small dirigible now being used by the French and British in hunting German submarines. The gas bag is short and stubby when compared to the latest rigid types of Zeppelins, and as a result, great speed is not possible. The car is the same as that used on English battleplanes, modified to an extent which allows slightly greater carrying
capacity.

Going to war in such a delicate contraption would be hard to imagine today.
What is that thing above the gondola? A torpedo tube?
That’s likely an air duct. Cool air beneath the balloon is pushed by the propellor between the outer layer and the gas-balloon to counter the balloons heating up during sunny weather. Which in turn reduces the buoyancy chance.
Most (if not all) dirigibles don’t have the entire envelope filled with the lifting gas. Instead, they have air-filled balloonets and gas bags – the air filled sections help control the expansion with altitude without valving off lifting gas, and also help keep the shape aerodynamic on non-rigid airships.
… and the air scoop is used to control the balloonets.
One war into the future, but still a fun fact: In WWII, no convoy escorted by blimps ever lost a single ship.

I’m not too keen on the slack cables in front of the propeller on the gondola. It looks basically like a observation balloon which normally has nothing more than a basket under it and is tethered to the ground. It’s a real kluge. I wonder if it was made by some nut who volunteered to go looking for subs in it.
