- I recently examined a close-up picture of the Space Shuttle, and I was
- puzzled by some of the design features. Please excuse my ignorance but:
-
- 1) Why is the tank so blunt? Isn't the shuttle a super-sonic vehicle?
- Shouldn't this be sharper, say one of theose secant ogive numbers?
-
- 2) Why is the tank so rough? Not only is the texture less than smooth,
- but there are a number of grooves near the front as well.
-
- 3) The struts that hold the shuttle to the tank are apparently naked
- cylenders. Shouldn't these be streamlined in some way?
-
- 4)On the side od each SRB, there is a piece of metal running lengthwise.
- Is this a strap to hold the segments together?
-
- 5) Wouldn't the SRB segments mate more reliably if the propellant grain
- from an upper segment extended into the next lower segment? That way,
- the propellant segments wouldn't coincide with the chamber segments and
- the infamous O-rings wouldn't take as direct a blast. No?
-
- Just curious. Thanks much.
