Introductio to AeroSpace 03a

OPENING QUESTION:  Why do you suppose that the Space Shuttle isn't an option for our "Most Significan Aircraft" presentation?

Now please work with your group and discuss the forces acting on the space shuttle during launch.

Now please work with your group and discuss the forces acting on the space shuttle during it's descent back to Earth.

LEARNING GOAL FOR TODAY:

WORDS O' THE DAY:

  • Force: ("A push or a pull")
  • Thurst ("forward pushing force")
  • Air Friction ("resists forward motion")
  • Lift ("Lower pressure, upward pull")
  • Weight ("downward pull")

WORK O' THE DAY:

Did you know that the US is still flying a space shuttle?

Yes indeed. The X-37B is a super-secret military shuttle. It doesn't have a crew and it recently set a record for duration in space at 717 days (almost 2 years!)

Notice that the X-37B is fairly small (Check out those itty bitty wings!) so it fits in a fairly standard launch rocket:

Notice all those black tiles... what's that all about?

 

 

1) To dissipate the immense heat of decent through the atmosphere using ceramic tiles glued to the shuttle:

The other HUGELY important design consideration was how to get the shuttle to generate lift on it's decent through the atmosphere. Otherwise, it will quite literally fall like a brick.

Let's take a gander at this and then discuss

Now let's review our specifications for our *MOST* significant airplane project

I'm happy to make revisions, so let's discuss

═══════════════════════════

Let's do a quick review of our 10 aircraft (that we need-to-know)

Now please take a few moments and do a *quick* look for 3 planes that you THINK might be possible candidates for your project
