They Are ACTUALLY Building THIS!
This video discusses the development of a full-size prototype blended wing body aircraft by a startup named Jet Zero. The primary advantage of this design is its potential for significant aerodynamic efficiency gains, estimated to be as high as 30%, which far surpasses recent improvements seen with new engines on traditional tube-and-wing airliners.
Key Idea 1: Blended Wing Body Design
- Concept: A blended wing body (BWB) aircraft integrates the fuselage and wings into a single lifting surface, offering improved aerodynamic efficiency.
- Comparison: Unlike pure flying wings, BWBs retain a fuselage but are designed to generate lift across a larger surface area.
Key Idea 2: Efficiency Gains
The BWB design promises substantial efficiency improvements. While new engines on aircraft like the Boeing 737 Max and Airbus A320 Neo offered about 14-15% efficiency gains, the BWB design aims for up to 30% through aerodynamic improvements alone. This is significantly higher than the 2-3% gains seen from airframe-related advancements in aircraft like the Boeing 787.

| Blended Wing Body | /ˈblɛndɪd wɪŋ ˈbɒdi/ | An aircraft design where the fuselage and wings merge into a single lifting surface. | The video discusses the Blended Wing Body design for increased efficiency. |
| Aerodynamic Efficiency | /ˌɛərəʊdaɪˈnæmɪk ɪˈfɪʃnsi/ | A measure of how effectively an aircraft’s shape generates lift and minimizes drag. | The aerodynamic efficiency of this new design is estimated to be up to 30% higher. |
| Startup | /ˈstɑːrtʌp/ | A newly established company, typically one with a new product or service. | A startup named Jet Zero is planning to build a full-size prototype. |
| Prototype | /ˈprəʊtətaɪp/ | An early sample or model built to test a concept or process. | Jet Zero plans to have an actual full-size prototype flying. |
| Airliner | /ˈɛərlaɪnər/ | A commercial aircraft designed to carry passengers. | Why would an airliner prefer a blended wing body over a traditional design? |
| Fuselage | /ˈfjuːsəlɑːʒ/ | The main body of an aircraft. | The fuselage of this aircraft still generates a considerable amount of lift. |
| Lift | /lɪft/ | The force that directly opposes the weight of an aircraft and holds it in the air. | The fuselage can also be aerodynamically stable, which isn’t necessarily the case for flying wings, but this fuselage still generates a considerable amount of lift. |
| Engines | /ˈɛndʒɪnz/ | The part of an aircraft that produces thrust. | Recent efficiency gains in airliners have come from new engines. |
| Boeing | /ˈbəʊɪŋ/ | A major American aircraft manufacturer. | Big names like Boeing aren’t building something like this. |
| Airbus | /ˈɛərbʌs/ | A major European aircraft manufacturer. | Airbus and other established aircraft manufacturers aren’t building something like this. |
