S. ships, the suspensions being adjusted to suit
the different makes of car.
In these ships the pilot sits in front, and behind him is the
wireless telegraphy operator; in several cases a third seat was
fitted to accommodate a passenger or engineer; dual rudder and
elevator controls are provided for the pilot and observer.
The engine is mounted aft, driving a four-bladed pusher
propeller, with the petrol tanks situated in front feeding the
carburettors by gravity. The engines used are Rolls Royce
Renaults, although in one instance a 75 horse-power Rolls Royce
Hawk engine was fitted, which assisted in making an exceedingly
useful ship.
S.S. ARMSTRONG WHITWORTH
The car designed by Messrs. Armstrong Whitworth is of the tractor
type and is in all ways generally similar to the B.E. 2C. The
single-skid landing chassis with buffers is the outstanding
difference. These cars had to be rigged to 70,000 cubic feet
envelopes otherwise the margin of lift was decidedly small. A
water-cooled 100 horse-power Green engine propelled the ship, and
a new feature was the disposition of petrol, which was carried in
two aluminium tanks slung from the envelope and fed through
flexible pipes to a two-way cock and thence to the carburettors.
These tanks, which were supported in a fabric sling, showed a
saving in weight of 100 lb.
