“…In the case of situational control of a small turbojet engine, a suitable and computational less intensive approach was taken in the form of combination of a rule-based expert system for indication of start-up and shutdown situations S 1 , S 2 , S 3 , and S 11 and a fuzzy inference system for indication of the remaining operational situations S 4 , … , S 10 .…”

“…The idea of utilizing small turbojet engines for rapid prototyping of algorithms and construction has also been pursued by other authors, Pecinka and Jilek designing a cost-effective test cell for small turbojet engines [6], application of small turbojet engines in education described in the works [7,8]. Small turbojet engines have also been used as testbeds in research of application alternative fuels for gas turbine engines using synthetic as well as biofuels in the works of Badami et al [9,10] or optimization of jet fuel combustion processes described in [11]. Small turbojet engines can be also used for aeroengines' component design and optimization as illustrated in optimization of turbine blades [12] or centrifugal compressors [13].…”

Improvements in reliability, safety, and operational efficiency of aeroengines can be brought in a cost-effective way using advanced control concepts, thus requiring only software updates of their digital control systems. The article presents a comprehensive approach in modular control system design suitable for small gas turbine engines. The control system is based on the methodology of situational control; this means control of the engine under all operational situations including atypical ones, also integrating a diagnostic system, which is usually a separate module. The resulting concept has been evaluated in real-world laboratory conditions using a unique design of small turbojet engine iSTC-21v as well as a state-of-the-art small turbojet engine TJ-100. Our results show that such advanced control system can bring operational quality of an engine with old turbocompressor core iSTC-21v on par with state-of-the-art engines. Dedicated to the memory of Ladislav Madarász

“…Many experiments executed both, on different types of real aircraft engines, as well as with the use of different alternative fuels were presented in the field of engine studies. Worth noting is the fact that the authors referred to the results of the research (Badami et al 2014), executed on a small-scale turbojet engine.…”

“…Numerous publications can be found in the literature (Ali and Nour 2017;Badami et al 2014;Baranski et al 2011;Canteenwalla et al 2016;Cavarzere et al 2014;Chiaramonti et al 2013;Chiariello et al 2014;Chishty et al 2011;Habib et al 2010;Hoxie and Anderson 2017;Ibrahim et al 2013;Mendez et al 2014), which are associated with testing different fuels with the use of small-scale turbine engines. It is worth emphasizing that currently fuels containing synthesized hydrocarbons obtained through five specific paths described in ASTM D7566-16 (2009) are approved for direct use as synthetic blending components (up to 50%) in aviation turbine fuels.…”

“…However, they can be an alternative power source for gas turbine engines for applications other than aviation. Only the following papers (Badami et al 2014;Baranski et al 2011;Canteenwalla et al 2016;Chishty et al 2011) concern the tests on small-scale engines in the scope of fuels: gas to liquid (GTL), hydroprocessed renewable jet (HRJ), synthetic aromatic kerosene (SAK), which may be used in aircraft turbine engines.…”

It is forecast that in the future, alternative fuels derived from non-petroleum sources will become the basic propellant for turbine aircraft engines. Currently, five types of aviation turbine fuel containing synthesized hydrocarbons are certified and accepted, and allow adding a maximum of 50% of synthetic component to conventional fuel. The experimental performance and the emission characteristics of a turbojet engine were investigated in this paper. The studies were conducted with the use of a miniature turbojet engine, which is the main component of a laboratory test rig. The test rig is an interesting solution for engine research, due to the fact that studies concerning fullscale aircraft engines are very complex and expensive. The literature of the subject contains many papers using smallscale turbojet engines for testing alternative fuels. However, most of them concern components of fuels, e.g. biodiesel, butanol, which do not have direct application in aviation. Two different fuel samples, a conventional Jet A-1 fuel and a blend of 48% synthesized paraffinic kerosene from hydroprocessed esters and fatty acids process with Jet A-1 were tested. This process is one of the routes of producing alternative fuel for aviation, approved by ASTM standard. The test rig studies were performed according to a specific profile of engine test, which models different modes of a turbojet engine's operation. The obtained results are compared in relation to the results for neat Jet A-1 fuel and then discussed.
