Small Aircraft Infrared Radiation Measurements Supporting the Engine Airframe Aero-thermal Integration

Abstract

The large, EU Supported ESPOSA (Efficient Systems and propulsion for Small Aircraft) project has developed new small gas turbines for small aircraft. One of the important tasks was the engine - airframe aero-thermal radiation integration that included task of minimizing the infrared radiation of the small aircraft, too. This paper discusses the factors influencing on the aircraft infrared radiation, its possible simulation and measurements and introduces the results of small aircraft infrared radiation measurements. The temperature of aircraft hot parts heated by engines were determined for validation of methodology developed and applied to engine - aircraft thermal integration.

Operators’ Load Monitoring and Management

“…The huge amount of available information confuses pilots during operation, particularly while decision-making in abnormal/emergency situations. While the introduction of new technology brings significant improvements and may solve some problems [ 25 , 26 , 27 , 28 ], it often introduces others in all transportation modes [ 29 , 30 , 31 , 32 ]. The future working environment of pilots (cockpit and future ground control towers) needs to be designed by taking into account various psychological and human factors.…”

Development of method of testing a set of screen-exhaust devices in the helicopter Mi-8MSB-B

“…Проведено чисельне дослідження з врахуванням геометричних розмірів, аеродинамічних та газодинамічних характеристик ЕВП з імітацією в польоті. А основні місця інфрачервоного випромінювання вертольоту були розглянуті авторами роботи [8]. Велику увагу автори приділили фону теплового випромінювання елементів обшивки фюзеляжу від розміщених під капотом двигунів.…”

Sliding Mode Control for Micro Turbojet Engine Using Turbofan Power Ratio as Control Law

“…For this reason, the transfer function of the plant has been established at a specified operating point, this was the nominal. The transfer function is shown in (19). The large magnitudes are due to the fuel supply rate being around 10 −3 kg/s at TPR with a magnitude of 1.…”

“…2.7495 × 10 9 s 3 + 3.612 × 10 3 s 2 + 9.172 × 10 5 s + 1.905 × 10 9 (19) All the PID controllers have been optimized by the integrated tuning tool in MATLAB R Simulink R . All controllers have been obtained as a parallel form, shown in (19), with filtered differential output to reduce the effect of input noise. The first PID controller was set to achieve the same settling time with the most possible robustness.…”

“…According to [18], results obtained on turbojet engine can be used to draw conclusions about non-propulsion power development units, which further enhances the role of turbojets in research applications. In several cases turbojets form the basis of a different development version like turboprop, as found in [19]. Variable nozzles are already being under investigation for turbofan engines as mentioned in [20], which system can also be assessed on turbojet engines ( [21] or [22]).…”
