National Symposium on Rotor Dynamics - IIT Madras

December 19,20,21

Most machines have one or more rotating parts. Rotating machine elements thus form the backbone of industrial infrastructure and therefore play a pivotal role in the growth and development of the country. Rotor Dynamics is the key in design and maintenance of all such rotating machinery. This area has made tremendous strides in recent years.

ObCom 2011 - VIT

September 9

This International Conference is a major event to be conducted following the grand success of series of ObCom conferences during 2003, 2004 and 2006, which were audited by a good number of participants from Academia and Industry across the World. The past ObCom conferences received good contributions from academia, industry and research organizations. Our sponsors included governmental and non-governmental agencies like DRDO, ISTE, DIT, CSIR etc.

Abstract:

The main thesis of this paper is to analyze the effect of inlet center body (spike) extending forwardly of the cowl inlet capture area of adjustable air inlet of variable geometry, for a supersonic aircraft, to continuously and effectively regulate the incoming air throughout the aircraft operating range of idle, subsonic, sonic and supersonic speeds. This is done by axially translating the inlet center body, for positioning of an external or initial shock wave front such that it extends conically between the apex of the spike and leading edge of the cowl for external
supersonic spillage of the air thereby regulating the engine air mass requirements. The main object is to provide inlet which is adjustable to match engine air flow characteristics while achieving high performance through high pressure recovery and low drag. In this a movable spike is utilized at supersonic speed for regulating both external supersonic low drag spillage and internal throat supersonic diffusion and the results are analyzed using CFX solver computationally.
