Why Space Shuttles Have a Blunt Nose: Aerodynamics and Safety …
2024年11月11日 · One of the most striking design features of a space shuttle is its blunt nose. Unlike the sharp, streamlined nose we might expect, a blunt nose spacecraft is better suited for the extreme conditions encountered during space shuttle re-entry.
The reason behind why a space shuttle has a blunt nose - YouTube
A supersonic aircraft that travels faster than sound has a sharp, pointed nose for better aerodynamic flow. On the contrary, a spacecraft entering the earth'...

2003年12月29日 · On an airplane, the elevator controls the motion of pitch (nose up, nose down). On most airplanes, the elevator is located on the horizontal stabilizer as part of the tail section. The ailerons are found on most airplanes at the trailing edge of each wing.
Why/when is the blunt nose better? - Aviation Stack Exchange
A blunt nose, however, will cause a separated shock. This creates more drag and a higher amount of heat overall, but allows to spread this heat over a larger area and dump most of it into the air, producing lower peak loads. The Space Shuttle had such a blunt nose, since drag minimization is not a priority for a re-entry vehicle.
The highest temperatures experienced were on the wing leading edge and nose cone. The time it took the Orbiter to start its descent from orbital velocity of about 28,160 km/hr (17,500 mph) to a landing speed of about 346 km/hr (215 mph) was 1 hour and 5 minutes. During re-entry, the Orbiter was essentially a glider.
Why was the nose cone on the Space Shuttle's external tank …
The original External Tank nose cone design was indeed blunt - almost like a fireplug, as seen in this 1975 concept art. [Image source - lost in the mists of time to me, but NASA somewhere] However, wind tunnel testing at the Arnold Engineering Development Center revealed that this configuration caused unsteady aerodynamic buffeting at some ...
Why were the Space Shuttle Orbiter's landing gear not level?
2021年6月24日 · The space shuttle lands at a high angle of attack (a very nose-up attitude) because of its delta wings. In order to provide adequate clearance to avoid a tail strike, the main gear needs to be long. Shuttle Crew Operations Manual - Section 4.9-1
Why is the space shuttle's nose round and not pointed?
2024年6月29日 · The Space Shuttle's nose is round because if it were pointed, the nose, and then the rest of the craft, would burn up from reentry into the earth's atmosphere. The space shuttle's...
