PBS TJ-100

Les turboréacteurs de la série TJ 100 ont été conçu comme unité de propulsion pour drones (MAE-UAV*), avions légers ou planeur.
Le développement de ce moteur a commencé en 2001, tandis que les premiers exemplaires de production étaient achetés par ITA en 2004. Plusieurs versions sont actuellement en production, qui se diférencient par des puissances, tuyères, fixations, ... différentes. Entre 2008 et 2019, plus de 1000 TJ100 auront été livrées.
PBS produit les TJ 100, TJ 100C, TJ100E, and TJ 100I d'une puissance de 100 daN (225 lbf), TJ 100A and TJ 100S d'une puissance de 110 daN (247 lbf).

Description
TJ 100 is single-shaft engine with single-stage radial compressor, annular combustion chamber, single-stage axial turbine, and stationary exhaust jet.
In the compressor intake there is a brushless starter generator, which enables the starting from the board network and power generating in course of the engine operation.
The intake air is compressed in the radial compressor wheel, proceeds through radial and axial diffuser into the combustion chamber, where it is mixed with fuel sprayed by several fuel nozzles. Combustion gases arising in fuel burning in the combustion chamber expand through the single-stage axial turbine and exhaust jet into the atmosphere.
The rotor of the engine is mounted on 2 ball bearings lubricated with pressure oil.
