Many people have commented that, although
this site is about the Stirling, there has been very little technical
information on the plane itself. Well here is the data page to finally
satisfy some of that demand. Its been a while coming while I check
my facts and figures as I don't profess to be an expert on this (or
any other) aircraft, but I hope this page will please those of you
with an interest in these details. Most pictures are courtesy of
'Aeroplane Magazine'.
The wealth of technical aircraft sites
on the Internet, and the many and varied publications on the subject,
will hopefully satisfy those 'techie's' with a need for such information
as wing spar construction, electrical wiring diagrams, and how the
Elsan chemical toilet worked, but for the rest of us I hope this
provides a brief glimpse (on an easy to follow, none 'techie' basis)
of the basics of the Short Stirling. Where possible I've tried to
use pictures below (which can be clicked for larger images) to illustrate
various points raised.
The Stirling was born because of a
need by the RAF to introduce a long range heavy bomber, capable of
carrying up to 14,000lb bomb loads, and being able to strike deep
into enemy territory. No other aircraft before it was capable of
satisfying this requirement, and left the country exposed as war
seemed inevitable in the second half of the 1930's. Of the companies
invited to tender specification for such an aircraft, Short Brothers
submitted a design (based around their successful Sunderland flying
boat) that was to become the Stirling.

The Stirling would enter service in
1940 and was based on a four-engined layout of just over 99ft wing
span, with a length of 87ft for the fuselage. Originally the design
specification had included a larger wing, but that had been overruled
by the Air Ministry (and would seriously alter its flying performance
from what had been intended). Even empty the aircraft would weigh
over 20 tons, but with its bomb load and 2250 gallons of fuel, this
would be a major factor in its maximum ceiling height of just about
17,000ft, especially with its 'clipped' wings producing less lift
than the original design.
The Stirling was powered by four Bristol
Hercules engines, each capable of producing 1600hp. These gave the
Stirling a top flying speed of around 270mph depending on weather
conditions and bomb load. Each engine was supercharged, and cooling
was by natural airflow over the engines. One of the problems encountered
with the engines was in the servicing by ground crews. With the tail
down the Stirling's nose was nearly 23ft from the ground, so care
was needed to avoid falling from the wings during routine maintenance!

The Stirling carried Browning .303
machine guns in three turrets, one turret below the cockpit for the
front gunner, a turret in the top of the fuselage just behind the
wings for the mid-upper gunner, and of course the usual tail turret
for the 'tail-end Charlie' or rear gunner. The Stirlings normal compliment
of seven crew was made up of the pilot and co-pilot, wireless operator/mid-upper
gunner, navigator/bomb aimer, flight engineer/mid-upper gunner, and
front and rear gunners.
The pilot and co-pilot sat high up
in the cockpit,

with the front gunner's turret below
them, and the bomb aimers window below that for maximum visibility.

Behind the cockpit was the navigator's
table,

and behind him a strengthened bulkhead
where the wings joined the fuselage. Behind the bulkhead to port
was the wireless operator's table and instruments,

and to his right on the starboard
side was the flight engineer's panel. The tail gunner was, as usual,
way out on his own at the back.
I hope this very brief data page helps
to illustrate the design, construction, and capabilities of this
heavy bomber......
