V. R. Prasad created a real-time linear model that is capable of assessing actual vehicle conditions to optimize performance during flight. The dynamic nature of the model provides greater accuracy in addressing the control needs of gas turbine aircraft, the backbone of commercial aviation.\u003C\/p\u003E\u003Cp\u003E\u201cUp until now, the models have been offline, and their results, very approximate,\u201d said Prasad, who headed up the research with his former doctoral student Gi-Yun Chung and Pratt \u0026amp; Whitney colleagues Manuj Dhingra and Richard Meisner.\u003C\/p\u003E\u003Cp\u003E\u0022This allows us to see what\u2019s happening at key stages of flight \u2013 typically take-off, cruising, and landing \u2013 where the demands on the aircraft, and its performance, can vary.\u201d\u003C\/p\u003E\u003Cp\u003EPrasad said widespread application of this real-time modeling in commercial air flight will inevitably result in greater fuel efficiency, more accurate engine maintenance, and increased air safety.\u003C\/p\u003E\u003Cp\u003E\u201cThis allows us to look at the health of the engine while it is in use, so you can see if it\u2019s getting close to its temperature or engine surge limits. Ideally, you want to operate within certain margins, and this allows us to control the plane so it operates optimally, without violating those limits.\u201d\u003C\/p\u003E\u003Cp\u003EThe patent represents the culmination of three years of dedicated research, supported by the Pratt \u0026amp; Whitney Center for Excellence. In June of last year, a paper describing the impact of that research, \u201cReal-time Linearization of Turbofan Engine Model\u201d was recognized with the 2013 Best Technical Paper award by the Controls Diagnostics \u0026amp; Instrumentation Committee of the American Society of Mechanical Engineers (ASME) at its Dusseldorf, Germany conference.\u003C\/p\u003E\u003Cp\u003E\u003Ca href=\u0022http:\/\/gasturbinespower.asmedigitalcollection.asme.org\/article.aspx?articleid=1734815\u0022\u003E\u003Cstrong\u003E\u003Cem\u003ERead more\u003C\/em\u003E\u003C\/strong\u003E\u003C\/a\u003E\u0026nbsp;about that research.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Research on real-time aircraft engine optimization conducted jointly by the School of Aerospace Engineering and Pratt \u0026 Whitney has resulted in a new patent."}],"uid":"27456","created_gmt":"2015-07-21 15:37:45","changed_gmt":"2016-10-08 03:19:12","author":"Britanny Grace","boilerplate_text":"","field_publication":"","field_article_url":"","dateline":{"date":"2015-01-05T00:00:00-05:00","iso_date":"2015-01-05T00:00:00-05:00","tz":"America\/New_York"},"extras":[],"groups":[{"id":"1239","name":"School of Aerospace Engineering"}],"categories":[{"id":"8862","name":"Student Research"}],"keywords":[{"id":"2082","name":"aerospace engineering"},{"id":"134471","name":"Gi-Yun Chung"},{"id":"129721","name":"JVR Prasad"},{"id":"54731","name":"Pratt \u0026 Whitney"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":["communications@ae.gatech.edu"],"slides":[],"orientation":[],"userdata":""}}}
