OUR NASA AIRPLANE

By Molly and Aleina

Ours is the best (boom)

HOW THE PARTS WORK TOGETHER

Four forces Propulsion Lift Fuselage

CRITERIA AND CONSTRAINTS Most go 500 miles Most hold 80 or more

people Must not use a runway

Must cost $76,000,000 or less

Must not use a runway

The situation we choose

The situation we choose was long haul. We are on a sports team at our school and we made it to the national championships. We have $76,000,000 to spend on our air craft. The rotors allow it to have no runway.

TRADEOFFS

GOOD BAD

The plane will not have a lot of downwash

Less noise Less fuel efficiency

We choose the stuff that costs the most

The body was heavy

LIFT SYSTEM We choose the 8 rotor lift system because it dose not have a lot of downwash.

ENGINE

We choose engine one because it has more power and scene it has more power it works good ,because are suppose to carry 81 people.

ESTELA HERNANDEZ

We choose her because she not only builds airplanes she is a pilot

too.

FUSELAGE We choose fuselage number 3. We choose it because it can hold more than 80 people.

Four forces

The four forces work together to make our plane move because drag makes it go backwards .Thrust makes it go forward. Lift pushes it up. Weight pushes it down.

OUR DESIGN

beginning ending

Smaller No propeller rockets

Bigger Propeller No rockets

OUR PLANE DID FLY Flew great Right distant Perfect time
