What is JetZero?

Today’s aircraft contribute around 4% of global CO2 emissions, equivalent to the emissions of 200 million cars. This is only going to increase: Air travel is forecasted to double by 2050, while meaningful efficiency gains using current airplanes have hit a wall.

JetZero is developing a blended-wing body (BWB) aircraft. It uses up to 50% less fuel and will be built to accommodate zero-emission hydrogen propulsion. JetZero is the inevitable solution to sustainable air travel.

The JetZero Team

We are experienced aerospace professionals and engineers, excited about the future. That future will only be possible if we share our vision and what it means to people’s lives: carbon-free flight that' is better for both passengers and airlines around the world.

What You'll Do

Develop, maintain, and validate aircraft and propulsion performance models supporting design, simulation, and flight test.
Own the engine performance model, including thrust, fuel flow, efficiency, bleed/power extraction, atmospheric effects, installation effects, and engine operating limits throughout the flight envelope.
Develop methods for in-flight thrust determination, using available engine parameters, aircraft state data, aerodynamic models, and flight-test measurements.
Perform engine model calibration and correlation against OEM performance data, ground-test data, and flight-test results.
Analyze propulsion and aircraft flight-test data to determine installed thrust, drag, excess thrust/power, specific fuel consumption, and overall aircraft performance.
As part of Flight Sciences, work closely with Propulsion, Aerodynamics, Flight Test, Systems, and Performance teams to establish consistent thrust and drag accounting methodologies.
Conduct aircraft performance analyses including takeoff, climb, cruise, descent, landing, range, payload, fuel burn, and reserves.
Develop tools and processes for flight-test performance reduction, including atmospheric normalization, data filtering, uncertainty assessment, and model correlation.
Support the definition of flight-test procedures and instrumentation requirements needed to validate engine and aircraft performance.
