Concetti Chiave
- Aircraft are vehicles capable of flight, including planes and hot air balloons, though control varies by type.
- Hot air balloons are a type of aircraft without motors, relying on wind for movement, unlike controllable gliders.
- Spacecraft are designed for travel in outer space, initially used for short trips and carrying animals.
- The space shuttle was a notable spacecraft for human missions, involving military and scientific endeavors.
- Fictional spacecraft like the starship Enterprise from Star Trek popularized space travel before it was feasible.
A vehicle that can fly
Aircraft at the air show
Ex: Several types of aircraft participated in the air show last weekend. The planes that flew close to the ground and performed barrel rolls were the most popular.
Ex: My grandmother rode in a hot air balloon, an aircraft without a motor, to celebrate her birthday. She was excited about it.
Although balloons move about with the wind, they are not really aircrafts because there is no way to control where they go. Even a glider has controls that let the pilot steer it. If you have ever made a paper airplane, you know it is difficult to control where it goes. It would not be called an aircraft. Kites and parachutes also move through the air without motors.
Paper airplane challenges
Ex: Even though John tried several times, he could not make his paper airplane land on the teacher's desk.
Ex: Because it doesn't have a motor, a glider must be controlled by the wind and the pilot's use of hand and foot controls to make a safe landing.
A vehicle that is capable of traveling in outer space
Ex: The earliest spacecraft made brief trips into outer space, and some of them carried animals rather than humans.
Ex: The shuttle was a spacecraft that carried both military officers and doctors or scientists who performed experiments in space.
Fictional spacecraft in media
Most people learned about spacecraft from science fiction books and movies before space travel was even possible. The most famous fictional spacecraft is the starship Enterprise from the Star Trek television show and movies.
Ex: Movies about spacecraft travel were popular before humans could actually travel to outer space.
Ex: Captain Kirk was the commander of the spacecraft known as the starship Enterprise during its travels in outer space.
Domande da interrogazione
- Quali tipi di veicoli hanno partecipato all'esibizione aerea?
- Come si controllano i veicoli aerei senza motore?
- Qual è il veicolo spaziale più famoso della fantascienza?
Diversi tipi di velivoli hanno partecipato all'esibizione aerea, tra cui aerei che volavano vicino al suolo e eseguivano manovre come i barrel rolls, risultando i più popolari.
I veicoli aerei senza motore, come i deltaplani, vengono controllati attraverso il vento e l'uso di comandi manuali e pedali da parte del pilota per garantire un atterraggio sicuro.
Il veicolo spaziale più famoso della fantascienza è l'astronave Enterprise della serie televisiva e dei film di Star Trek.
