Ed Haering

Technical Lead for Supersonic Aerodynamic Research at Armstrong

Sonic boom research, air data measurement, GPS, and ground-based radar

Manages concept and experiment design through test execution and analysis


The Goal Everyone wants to go fast

But there is a problem

Plane reaches supersonic speed creates a sonic boom

Historically, civil supersonic speeds flown only over water

Sonic booms must be managed for supersonic flight over land


And how loud can they be?

What is a Sonic Boom?

A loud explosive noise caused by the shock wave from an aircraft traveling faster than the speed of sound

sonic boom snik boom, noun


Key factors impacting sonic booms

Aircraft & engine configuration or shaping

Aircraft weight

Temperature Wind

Humidity

Speed Altitude

Dive Angle Acceleration

Terrain & topography


What can we do about sonic booms?

Develop novel aircraft shapes & propulsion systems

NASAs High Speed Project Key element is advanced

computer-based prediction methods for supersonic aircraft shape and performance

Sonic Boom Sonic Puffs



Fly in the Mach cutoff zone

M < 1.11.3, refraction may prevent boom from reaching the ground

Noise heard like rumble of distant thunder or nothing at all


Determine and understand acceptable annoyance NASA Armstrong has conducted studies to assess magnitude

of booms and their impact on the public (e.g., FaINT, WSPR)

Predict booms and enable planning to avoid booms or place them in appropriate locations


Solution: NASAs Real-time Sonic Boom Display


Real-Time Sonic Boom Display Benefits

Real-Time Sonic Boom

Display

Use in real time

Predicts shock wave location & intensity

Pilots can control

intensity & location of booms

Use in planning

Functional in a cockpit or

flight control room

Sonic Boom Basics

Mach Cone and Ray Cone Shock waves generated at the aircraft can take several minutes to propagate forward on the ray cone to the ground

Boom footprint generated from aircrafts current location

Future Development


NASAs High Speed Project is developing and validating tools and technologies to enable practical high speed vehicles

Boom prediction and placement are key components

Real-Time Sonic Boom Applications


Several commercial companies are working to design aircraft that can achieve overland supersonic travel



Federal Aviation Administration Air traffic controllers will need to approve flight plans, monitor aircraft in flight, and review flight data to enforce regulations Technology could intelligently route supersonic aircraft and limit acoustic signatures to acceptable levels



Real-Time Sonic Boom Market

Sonic boom display .125% of aircraft cost

300-500 supersonic aircraft over 10 years Aircraft cost about $80M and a bunch

Air Traffic Control also requires displays


NASAs Next Steps

Cockpit display in 2014

Integration with low boom

demonstrator

Seeking partners for development

Now What?


NOW IS THE TIME TO GET INVOLVED AND BE PART OF THIS SOLUTION

Opportunities

Collaboration & Commercialization

Co-development under research

agreement

Licensing opportunities
