Sonic Boom Calculator
About the Sonic Boom Calculator
The Sonic Boom Calculator is a scientifically accurate online tool that predicts the intensity, arrival time, and ground footprint of a Sonic Boom generated by supersonic aircraft using Whitham’s F-function, ray tracing, and NASA boom propagation models. It computes peak overpressure ΔP, N-wave duration, boom carpet width, and atmospheric refraction effects. Developed with support from Agri Care Hub, this tool is trusted by aerospace engineers, urban planners, and researchers worldwide.
Importance of the Sonic Boom Calculator
A sonic boom is a shock wave "thunder" heard when an object exceeds the speed of sound, forming a conical shock system (Mach cone). It causes noise pollution, structural vibration, and public concern. This calculator instantly predicts boom strength at ground level — critical for supersonic transport (SST) certification, flight path planning, and noise regulation. Manual prediction using CFD or wind tunnel data is expensive; this tool delivers real-time, peer-reviewed results using validated sonic boom theory from NASA CR-1299 and FAA regulations.
User Guidelines
To use the Sonic Boom Calculator:
- Profile: Level cruise, dive, or ground boom carpet.
- Mach M: Supersonic speed (M > 1.0).
- Altitude h: Flight level in meters.
- Length L: Aircraft fuselage length.
- Weight W: Gross takeoff weight.
- Temperature & Humidity: For atmospheric absorption.
- Calculate: Get ΔP, boom width, arrival time.
Default: Concorde-like SST at FL500.
When and Why You Should Use the Sonic Boom Calculator
Use this tool when you need to:
- Assess Noise Impact: Predict community annoyance.
- Design Low-Boom Aircraft: Shape for reduced ΔP.
- Plan Flight Corridors: Avoid populated areas.
- Comply with Regulations: Meet ICAO/FAA boom limits.
- Teach Supersonic Flow: Demonstrate Mach cone and N-wave.
It ensures safety, sustainability, and public acceptance of supersonic flight.
Purpose of the Sonic Boom Calculator
The tool aims to:
- Quantify Boom Intensity: Make ΔP predictable.
- Support SST Revival: Enable quiet supersonic travel.
- Enhance Learning: Reinforce shock coalescence and ray acoustics.
- Promote Harmony: Balance technology with environment.
Scientific Foundation: Whitham’s Theory
Peak overpressure (far-field):
ΔP ≈ (0.3 K M² √(W/L)) / h^{3/4}
Mach cone angle:
μ = arcsin(1/M)
Boom carpet half-width: w = h √(M² − 1)
Atmospheric Effects
Temperature gradients cause ray bending (caustics).
Humidity and wind affect high-frequency absorption.
