Scaling methods for simulating aircraft in-flight icing encounters (OCoLC) Microfiche version: Anderson, David N. Scaling methods for simulating aircraft in-flight icing encounters (OCoLC) Material Type: Document, Government publication, National government publication, Internet resource: Document Type: Internet Resource, Computer File. This paper discusses scaling methods which permit the use of subscale models in icing wind tunnels to simulate natural flight in icing. Natural icing conditions exist when air temperatures are below freezing but cloud water droplets are super-cooled : Gary A. Ruff and David N. Anderson. Scaling methods for simulating aircraft in-flight icing encounters / by: Anderson, David N.,, et al. Published: () An overview of NASA engine ice-crystal icing . tunnel testing of sub-scale complete aircraft models to identify the integrated effects of icing on the aircraft system in terms of performance, stability, and control. Data sets of this nature enable pilot in the loop simulations to be performed for pilot training, or engineering evaluation of system failure impacts or control system Size: 5MB.

This paper reviews experimental and computational methods used for simulation of ice accretion on aircraft flying through icing conditions. Such methods were recently reviewed by the AGARD FDP Working Group 20 and the present paper represents a revised and updated version of parts of the Working Group by: FENSAP, part of the FENSAP-ICE aerodynamics and icing simulation system. The paper will present results of flow, droplet impingement and ice accretion on a complete helicopter, including main and tail rotors in hover and forward flight, and the BA tiltrotor aircraft in airplane mode. All rotating components will be modeled as actuator disks. The instructors bring an amalgam of knowledge, as scientists who have produced codes in current use and practicing engineers with experience in cost-effective methods for the certification of aircraft for flight into known icing conditions. Abstract. A modified icing scaling law, derived from the basic process of ice accretion on aircraft surface, is proposed in this paper. Numerical method is used for evaluation of the modified icing scaling Cited by: 1.

Version 1 Aircraft Icing Handbook Chapter One 6 14 June De-icing is a procedure in which frost, ice, or snow is removed from the aircraft in order to provide clean surfaces. Anti-icing is a process that provides some protection against the formation of frost or ice for a limited period of time. One method involves flight tests with the attachment of artificial ice shapes on the non-protected surfaces of the aircraft. These shapes are in turn determined by simulated icing encounters. Icing has always destructive effects on drag and lift forces so the overall performance of aircraft will deteriorate. Moreover, icing would impact on stability and control of the aircraft. Simulation of aircraft icing is of great importance to investigate the flow field and its effects on aerodynamic characteristics. limitations of the simulation methods in terms of how well they function with respect to their stated purpose and how well they simulate natural icing encounters.
