RWPS Rotary Wing Performance Surface

A session at FOSS4G North America 2013

Wednesday 22nd May, 2013

11:00am to 11:30am (CST)

Helicopters don’t fly; they beat the air into submission. You might be surprised how close the helicopter vs. gravity fight can be with active military assets. The winner can be predicted with complex equations that use aircraft performance functions, terrain elevation, weather conditions, and aircraft loaded weight. A single aircraft’s maximum takeoff and hover weights can vary hundreds of pounds from place to place and day to day. Predicting this maximum load is very important to mission planning and execution. Transport pilots often want to minimize their number of sorties by carrying as much cargo as possible each time. Attack pilots surely don’t enjoy running out of ammunition and often want to bring as much as the conditions and airframe support. Existing concept of operations has rotary wing pilots compute the power margins for their take-off and target locations by hand using old-fashioned-engineer style look-up curves and weather condition point forecasts.

Geocent’s Rotary Wing Performance Surface efforts produced a web-based tool backed by Geoserver’s WPS that computes the power margin for specific airframes using WCS weather forecast models. The resulting 4-D mapping service can be viewed in existing mission planning tools and users can have slider bars to adjust time of day and aircraft weight. Not only does this tool provide pilots a complete view of their performance battlespace, but it also provides ground commanders and mission-planners predictions of where they can count on having medevac rotary wing support.

The presentation will provide an overview of the RWPS tool and the critical Special Operations Mission Planning concerns addressed. The methods used for web based GIS performance modeling will be discussed for generalized applications.
