  • Electrically Heated Composite Leading Edges for Aircraft Anti-Icing Applications”
    UNIVERSITY OF NAPLES “FEDERICO II” PhD course in Aerospace, Naval and Quality Engineering PhD Thesis in Aerospace Engineering “ELECTRICALLY HEATED COMPOSITE LEADING EDGES FOR AIRCRAFT ANTI-ICING APPLICATIONS” by Francesco De Rosa 2010 To my girlfriend Tiziana for her patience and understanding precious and rare human virtues University of Naples Federico II Department of Aerospace Engineering DIAS PhD Thesis in Aerospace Engineering Author: F. De Rosa Tutor: Prof. G.P. Russo PhD course in Aerospace, Naval and Quality Engineering XXIII PhD course in Aerospace Engineering, 2008-2010 PhD course coordinator: Prof. A. Moccia ___________________________________________________________________________ Francesco De Rosa - Electrically Heated Composite Leading Edges for Aircraft Anti-Icing Applications 2 Abstract An investigation was conducted in the Aerospace Engineering Department (DIAS) at Federico II University of Naples aiming to evaluate the feasibility and the performance of an electrically heated composite leading edge for anti-icing and de-icing applications. A 283 [mm] chord NACA0012 airfoil prototype was designed, manufactured and equipped with an High Temperature composite leading edge with embedded Ni-Cr heating element. The heating element was fed by a DC power supply unit and the average power densities supplied to the leading edge were ranging 1.0 to 30.0 [kW m-2]. The present investigation focused on thermal tests experimentally performed under fixed icing conditions with zero AOA, Mach=0.2, total temperature of -20 [°C], liquid water content LWC=0.6 [g m-3] and average mean volume droplet diameter MVD=35 [µm]. These fixed conditions represented the top icing performance of the Icing Flow Facility (IFF) available at DIAS and therefore it has represented the “sizing design case” for the tested prototype.

  • A “Short Course” on Ice and the TBM
    A “Short Course” on Ice and the TBM. Icing is topical at the present time as a result of a recent accident in a TBM. I have had a number of conversations with pilots who I would consider knowledgeable and it is apparent that there is a lot of confusion surrounding this subject. Also noting on line posts this confusion is not limited to owner pilots. I have had occasion to be a victim of my own stupidity in a serious icing condition years ago and I can vouch that icing is a deadly serious situation in more ways than one. Before going on with the subject we want to stipulate that the data we are about to provide is a summary of information that is to be found on line, along with narrative and data provided from knowledgeable instructors, if any of the data provided conflicts with anything you have been taught we urge you to satisfy yourself as to which data is correct. TBM operators fly in the same airspace where we find Part 25 aircraft (Commercial Category) aircraft. There is a big difference in how these two categories of aircraft are affected by icing conditions. A 767 will often be climbing at over 300 kts and 4000+ ft/min at typical icing altitudes. This creates two very distinct advantages for the 767: first, their icing exposure time may be less than 1/3 of ours. Second, icing conditions are a function of TAT (Total Air Temperature), not SAT (static air temp). TAT is warmer than SAT because of the effects of compressibility as the airplane operates at faster and faster speeds.

ACTION: Notice of proposed rulemaking (NPRM). SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD) 2020-23-13, which applies to all ATR – GIE Avions de Transport Régional Model ATR42-200, -300, and -320 airplanes. AD 2020-23-13 requires a one-time inspection for discrepancies of the wire bundles between the left- and right-hand angle of attack (AOA) probes and the crew alerting computer, and, depending on findings, applicable corrective actions. Since the FAA issued AD 2020-23-13, a wiring modification for the captain stick shaker has been developed, along with an update to the aircraft flight manual (AFM). This proposed AD would continue to require the actions in AD 2020-23-13. This proposed AD would also require, for certain airplanes, modifying the captain stick shaker wiring, and for all airplanes, revising the existing AFM and applicable corresponding operational procedures to incorporate procedures for the stick pusher/shaker, as specified in a European Union Aviation Safety Agency (EASA), which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products. DATES: The FAA must receive comments on this proposed AD by [INSERT DATE 45 DAYS AFTER DATE OF PUBLICATION IN THE FEDERAL REGISTER].
