History
The history of PBS VB has been closely related to the company PBS Brno, originally founded in 1814 by Jan Reiff, who established a textile mill nearBrno
Brno ( , ; german: Brünn ) is a city in the South Moravian Region of the Czech Republic. Located at the confluence of the Svitava and Svratka rivers, Brno has about 380,000 inhabitants, making it the second-largest city in the Czech Republic ...
. As the company was growing, new facilities were built. PBS VB was established in 1950 in Velká Bíteš
Velká Bíteš (until 1924 Velká Byteš) is a town in Žďár nad Sázavou District in the Vysočina Region of the Czech Republic. It has about 5,200 inhabitants. The historic town centre is well preserved and is protected by law as an urban mon ...
, Czech Republic to support industrial development of the region.
The first products produced in PBS VB were hammer drills and parts for mining and metallurgical pneumatic tools. In 1951 a production of fittings started.
Modernisation and extension of the production capacities connected with an investment casting hall construction were finished in 1970. At the same time, the company entered the aviation world by developing an auxiliary power unit for Aero L-39 Albatros aircraft.
After gaining experience in the technology of auxiliary power units and environmental control systems, in 2004 PBS VB expanded its product portfolio and included propulsion units – turbojet, turboshaft and turboprop engines for small manned or unmanned aircraft, UAVs and target drones.
PBS VB delivers its products globally and since the 1970s more than 7,000 pieces of turbine equipment for the aerospace industry has been manufactured in PBS VB in total.
