Parameter Identification for Inflightdetection of Aircraft Icing ?

Study the effect of nano Al2O3 and nano graphene ceramic additives on the aircraft anti-icing/de-icing fluids

In the present study, the effect of nano Al2O3 and nano graphene ceramic additives in optimizing performance and improving thermophysical properties of aircraft anti-icing/de-icing fluids was investigated. Nanoparticles were characterized by TEM, SEM and XRD methods. The thermal conductivity, surface tension and dynamic viscosity of the hybrid nanofluids were experimentally assessed for tempera...

Parameter Identification for Inflight Detection and Characterization of Aircraft Icing

Neural Network Based Icing Identification and Fault Tolerant Control of a 340 Aircraft

This paper presents a Neural Network (NN) identification of icing parameters in an A340 aircraft and a reconfiguration technique to keep the A/C performance close to the performance prior to icing. Five aircraft parameters are assumed to be considerably affected by icing. The off-line training for identifying the clear and iced dynamics is based on the LevenbergMarquard Backpropagation algorith...

بررسی شرایط هواشناختی یخ‌زدگی هواپیما در دو بررسی موردی (فرودگاه مهرآباد-تهران)

Ice can form on aircraft surface at 0° C or colder temperatures when liquid water is present. This can happen both on the ground and at the flight levels of the aircraft. Aircraft icing has not only an impact on flight safety but has also an economic impact. According to the report of research department of the FAA (Federal Aviation Administration), from 1982 to 2001, 13% of accidents due to ai...

Near-real time cloud properties and aircraft icing indices from GEO and LEO satellites

Imagers on many of the current and future operational meteorological satellites in geostationary Earth orbit (GEO) and lower Earth orbit (LEO) have enough spectral channels to derive cloud microphysical properties useful for a variety of applications. The products include cloud amount, phase, optical depth, temperature, height and pressure, thickness, effective particle size, and ice or liquid ...
