Svenska
Aero AB designed three aircraft in their Falken (Falcon) series - the
SA-11 Jaktfalken (”Fighter Falcon”), the SA-12 Skolfalken
(”Trainer Falcon”) and
the SA-13 Övningsfalken (”Advanced Trainer Falcon”). First
out was SA-12 Skolfalken.
The
company had not achieved much success with its previous project, the
SA-10 Piraten. But never the less - despite the setback and despite
little interest from the Air Force - Svenska Aero started the design
work of an universal trainer aircraft. It would be built in two versions
- the basic (Type I) trainer SA-12
Skolfalken and the advanced (type II) trainer SA-13
Övningsfalken.
The
first SA-12 Skolfalken was manufactured as a speculation in 1929. Pilots
from the Air Force were hired for the test flights, which took place at
Barkarby near Stockholm with start in September the same year. The tests
were successful and the managing director of Svenska Aero AB - the
well-known aviator and aircraft designer Carl Clemens Bücker, managed
to sell the aircraft to the Air Force. The Skolfalken got the official
designation Sk 8 and the Air
Force registration number 5100.
The
aircraft was transferred to the Air Force Flight Academy at Ljungbyhed (F 5).
Some modifications were made. The most important was a new fin and
rudder. The flying instructors at Ljungbyhed were very pleased with
their Sk 8 and would not mind the Air Force replacing the old Sk 6
Heinkel trainers
with the Sk 8. But,unfortunately for Svenska Aero, the Sk 6’s,
with its unreliable surplus engines, hastily had to be grounded for
good. There was no time to wait for deliveries from Svenska Aero.
Instead, ten de Havilland DH 60T Moth Trainers (Sk 9) were purchased and delivered in 1931. The time between order
and delivery was only two months.
The
single Sk 8 continued to fly at F 5 for some years. Later it was
transferred to F 3 at Malmen, where it was written off in 1938 after 386
hours of use. The story of the single Sk 8 was definitely over in the
spring next year, when the aircraft was used as a May bonfire
(see photo below).
The
Sk 8 was powered by a 5-cylinder Armstrong Siddeley Mongoose air-cooled
radial engine of 135 hp. One single aircraft of the above mentioned
variant SA-13 Övningsfalken was also built. It was mainly the same
design, but powered by a stronger engine. See Ö
8!
Svenska
Aero was more fortunate with the fighter Jaktfalken. 1+17 aircraft were
purchased by the Air Force, designated J 5 and J 6.
