Podlaska Wytwórnia Samolotów (PWS; Podlachian Aircraft Factory) was a Polish aerospace manufacturer between 1923 and 1939, located in Biała Podlaska.

History

[edit]

Podlaska Wytwórnia Samolotów SA was created in 1923. The first aircraft produced were 35 Potez XV bombers for the Polish Air Force, under the French licence, built from 1925.[2] By 1929 the company had produced 150 Potez XXV and 155 Potez 27, under French licence, and 50 PWS-A fighters, which was the Czech Avia BH-33 built under licence. It also produced 50 Bartel BM-4 trainers in 1931, designed by Samolot.[2]

In 1925, a design office was established which included, among others, Stefan Cywiński, Zbysław Ciołkosz, August Bobek-Zdaniewski.[2] Despite a large number of prototypes, few were produced in series. The first aircraft of their own design to be mass-produced was the PWS-10 fighter of 1930 of which 80 examples were built. Smaller production runs of the PWS-14 trainer and the PWS-24 passenger aircraft were also made. The PWS-10 and PWS-24 were the first fighter and the first passenger plane of the Polish construction built in series, respectively. In 1929 the factory built a wind tunnel, the first in Poland. All PWS-designed aircraft had wooden or mixed construction.[2]

In 1932 the PWS was nationalized to prevent its bankruptcy.[2] It then produced 500 RWD-8 trainers (designed by RWD) and 50 of the British Avro Tutor under licence as the PWS-18 trainers.[2] The factory then designed its own successful PWS-16 and PWS-26 advanced trainers, 320 of the latter built from 1936 to 1939.

In 1936 the factory was subordinated to the Państwowe Zakłady Lotnicze (PZL). It developed a series of projects for military planes, but they were not built due to outbreak of World War II. The PWS-33 Wyżeł twin-engine advanced trainer and the PWS-35 sports biplane were ordered into production but no aircraft were delivered before the outbreak of war.

Lwowskie Warsztaty Lotnicze (LWL, Lwów Aviation Workshops) was formed in October 1937 as a division of PWS. It built gliders, among others designated with letters PWS. Some 160 gliders were built before the war.[3]

After the outbreak of World War II, the PWS factory was bombed by the Germans on September 4, 1939, who destroyed about 70% of the factory. The remains of equipment were plundered by the Soviets after their invasion of Poland.
