Development of a Predictive Model of Jet Blast Exposure In Reserve

Last Edited by Gael Le Bris

The goal of this research idea is to develop a predictive model of jet blast exposure based on local parameters (taxiway slope, operating conditions, aircraft operator practices, temperature, types of aircraft, etc.). This model will be based on jet blast measurements performed at various airports of different size and traffic in the U.S.

Background (Describe the current situation or problem in the industry, and how your idea would address it.)

Airport design standards do not include specifications or comments related to jet blast hazard, except for the risk of erosion on the areas surrounding the runway and the aeraulic effects that could create an aircraft taxiing on a bridge. However, jet blast generates risks before the runway and outside taxiway bridges. It can endanger infrastructures, equipment and persons on the movement and non-movement areas, while the apron naturally increases the level of risk by bringing close together operating aircraft, vehicles, equipment, workers and passengers.

There is few guidance on jet blast hazard assessment and very light literature on jet blast exposure. However, research findings from The French-Speaking Airports (see link below) and the Aircraft Characteristics for Airport Planning manual of the Boeing 737 MAX confirm that local parameters such as the slope and the use of one engine taxiing procedures have a significant impact on jet blast.

A research project conducted at Paris-CDG showed that predicting jet blast exposure based on local parameters is feasible, through a function of local parameters significantly influencing jet blast exposure such as pavement slope, type of aircraft, and airfield operating procedures. The model based on 300 observations made in 2015 can help in confirming low-blast exposure. However, the development of a robust quantitative estimation of jet blast exposure for planning and design purpose requires supplemental efforts of data gathering on the field at different airports.

Approach (Describe in general terms the steps you think are needed to achieve the objective.)

- Conduct jet blast measurements at various U.S. airports: the set of airports should include general aviation and commercial service airports, and should capture observations of aircraft of all sizes and types.
- Confirm significant parameters and develop predictive model.
- Develop an electronic tool based on this model.

Cost Estimate and Backup (Provide a cost estimate and support for how you arrived at the estimate.)

- Cost estimate: $350,000
- Duration: 16 months

The project includes jet blast measurement campaigns in the field.
