První brněnská strojírna introduced the PBS TJ80 aircraft engine to the market

The joint‐stock company První brněnská strojírna Velká Bíteš (PBS) follows the current worldwide trend of the growing use of unmanned aerial vehicles; it developed a new turbojet engine specifically for such aircraft. Today, the range of applications of unmanned aerial vehicles is constantly on the rise. These aren’t just drones intended for the monitoring of weather, carrying equipment for the measuring of radiation or used for the monitoring of oil and gas pipelines; we speak of drones with a much wider range of applications. PBS is, therefore, flexibly reacting to the demand for new engines which are mostly intended for training targets and other unmanned applications.

The new PBS TJ80 turbojet engine with a thrust of 900N presents the next development stage of the engine programme at PBS and its beginnings date back to the year 2002. At that time, development was started on the first and the best selling turbojet engine to date, the PBS TJ100. Its development at the time took two years, which is the same amount of time as the development of the PBS TJ80. Currently, there are 20 modifications of this engine available, made to meet the specific requirements of customers. In less than 15 years, more than 800 of these engines were sold.

Nevertheless, many years have passed since then and the market’s requirements became significantly more strict. Small aircraft engines slowly found use not only in piloted aeroplanes and helicopters but mainly also in unmanned aerial vehicles. The requirement for the optimization of the power to weight ratio of the engine grew significantly, just like the demands on the installation dimensions.

The PBS TJ80 engine thus conforms to the strict requirements of the market and offers much more. This engine in comparison with its competitors is noticeably lighter, more compact, and at the same time it excels with its great parameters at high speeds and high altitudes. It is designed both for applications taking‐off from the ground and also from the air. This light and powerful model is able to reach its maximum thrust in a matter of seconds. Among its main features is its ability to start in any positions and the option to repeatedly start at a speed of 0.6 M. Another unquestionable advantage is the absence of an oil system. The engine is lubricated only with fuel.

“I’m proud of the design and technical team at PBS, which was able to develop and launch into serial production our new engine, the PBS TJ80, in only a two years of time. On top of that, we’ve begun working in parallel on our most powerful engine, the PBS TJ150, which is currently in its last development stage; we plan to introduce it on the market at the end of this year,” said Milan Press release 06/2018 Macholán, the CEO of PBS Velká Bíteš. “Judging from the preliminary interest in the PBS TJ80 engine, I believe that in the near future it will rank among our best selling products,” he adds.

PBS Velká Bíteš is continuously expanding its line of turbojet engines. Its products include the first PBS TJ100, followed by the TJ20, TJ40 and now the TJ80, and in the near future the company plans to introduce the PBS TJ150. If we also add to this list the turboprop and turboshaft engines, the company’s comprehensive portfolio of aircraft engines is a strong branch in the company’s aircraft business, right next to the area of auxiliary power units (APU). Currently, PBS is one of only a few brands in the world with the authorization for the development, certification, manufacturing and maintenance of aviation equipment which is granted by the European Aviation Safety Agency (EASA).
