A key difference between a space shuttle and an aeroplane lies in their operational principles: space shuttles do not fly like aeroplanes.
Flight Mechanics
| Feature | Aeroplane | Space Shuttle |
|---|---|---|
| Flight Type | Sustained atmospheric flight | Ballistic projectile on ascent; Glider on return |
| Lift | Achieved through aerodynamic lift generated by wings. | No aerodynamic lift on ascent; aerodynamic lift achieved on descent without thrust. |
| Thrust | Provided by engines throughout the flight | Only for initial ascent; no thrust during reentry and landing |
Detailed Explanation
Here's a deeper look at the differences:
-
Aeroplanes:
- Utilize wings to generate lift by manipulating airflow.
- Employ engines for continuous thrust throughout the flight to maintain lift and forward motion.
- Are designed to operate primarily within Earth's atmosphere.
- Examples include commercial jets, private planes, and military aircraft.
-
Space Shuttles:
- Ascent Phase: On the way up, the shuttle is a ballistic projectile propelled by rocket engines; it doesn't use its wings for lift in the atmosphere; it is thrust based, not lift based.
- Descent Phase: When returning, it acts as a glider without engine power, relying solely on aerodynamic lift to control its descent back to Earth.
- Designed to function in the vacuum of space and return through Earth's atmosphere.
Key Differences Summarized
- Thrust and Lift: Aeroplanes maintain flight with continuous thrust and aerodynamic lift, while space shuttles use thrust for ascent and aerodynamic lift only during unpowered descent.
- Flight Mode: Aeroplanes continuously fly with lift and thrust, while space shuttles only glide down from space, and are essentially rockets ascending, not an aeroplane.
- Operational Environment: Aeroplanes operate primarily within the atmosphere, while space shuttles travel to and from space.
In conclusion, according to the reference, a space shuttle is never a plane in either phase of its trip, as it is either a ballistic projectile or a glider, neither of which are true planes.
