Filtration and Contamination Control for Aerospace Hydraulic Systems C1206


This four-hour short course provides an introduction to contamination control principles in aircraft hydraulic systems. Topics covered include an introduction to the types of contamination in aircraft hydraulic systems, contaminant measurement, and reporting methods. In addition, the impact of contamination on hydraulic components is discussed in detail. Along with an introduction to filtration mechanisms, information on testing, rating, and specifying filters will be provided.


Learning Objectives
By attending this seminar, you will be able to:
  • Associate the types of contaminant in aircraft hydraulic systems and the problems that uncontrolled contamination can cause
  • Interpret a particle count or contamination level report
  • Identify how filters work and are evaluated
  • Explain filter ratings
  • Formulate a basic specification for hydraulic filters

Who Should Attend
The course is intended for engineers with some basic knowledge of hydraulic systems, but with minimal experience with the impact of contamination and specifications of filtration products for controlling it.

Puliyur Madhavan is a Research/Engineering Fellow at Pall Aerospace, a division of Pall Corporation. His expertise is in filtration technology for Aerospace fluid systems such as hydraulic, lubrication, fuel, and air systems on-board aircraft and military land and sea vehicles.

He is a member of several technical standards development organizations including the SAE AE-5 Committee (Aerospace Fuel, Inerting and Lubrication Systems) and the SAE E-34 Committee (Aerospace Propulsion Lubricants), and he has worked on programs with the IATA Fuels Group. He has published numerous articles and technical papers related to contamination control in aerospace fluid systems, and he is also the author of a number of technical papers and SAE standards related to filter performance evaluation and filter debris monitoring.

Puliyur Madhavan received his doctorate in Chemistry from the State University of New York at Stony Brook in 1982. He did post doctoral research work at the Brookhaven National Laboratory and at the State University of New York at Stony Brook where he also held a joint position as lecturer in the Materials Sciences Department for several years. He joined Pall Corporation in 1987 and has held various technical and management roles in the company over the last 32 years.
