Question
Select which of the following statements are True and which are False.
Remember, for a statement to be True, it must be totally and completely True.
Given the same flight path angle, a re-entry vehicle with a higher Vre-entry will experience the maximum deceleration at a higher altitude than a re-entry vehicle with a lower Vre-entry
Given the same flight path angle, a re-entry vehicle with a higher Vre-entry will experience a maximum heating rate at a higher altitude than a re-entry vehicle with a lower Vre-entry
Given the same Vre-entry, a re-entry vehicle with a steep flight path angle, , will experience a maximum heating rate at a higher altitude than a re-entry vehicle with a shallow flight path angle
Given the same Vre-entry, a re-entry vehicle with a steep flight path angle, , will experience maximum deceleration at a lower altitude than a re-entry vehicle with a shallow flight path angle
The maximum heating rate on a re-entry vehicle is the same regardless of its Vre-entry or its flight path angle,
The most accurate landing of a re-entry vehicle is provided by a trajectory design that provides a large Vre-entry and a steep flight path angle,
A mission design team can greatly effect the maximum deceleration on their re-entry vehicle by adjusting the vehicle's Ballistic Coefficient, that is selecting between a highly streamlined or very blunt shape for the re-entry vehicle.
Producing a re-entry vehicle with a high Ballistic Coefficient (BC) will mean the re-entry vehicle will plunge far into the atmosphere before reaching maximum deceleration.
Research into the materials used in the nose cone of a ICBM's
An ablative heat shield (Thermal Protection System or TPS) for a re-entry vehicle is based upon a principle called the Latent Heat of Fusion - the same reason that keep drinks coldest -- melting ice cubes will keep a drink colder and for longer than one of those little "whiskey stones", a little rock that you put in the freezer and then into your drink. The stone won't melt and water down the drink, but that misses the point of using water-ice cubes. It isn't the coldness of the ice, it is the process of melting the ice which keeps things cold.

1.False
2.True
Explanation / Answer
A : False, As Vre-entry in vertical= Vre-entry * sin(theta) and since sin(theta) is same in both case, so one having heigher Vre-entry will have less deceleration.
B : True
C: True
D: False
E: False
F: True
G: True
H: True
I: False
J: True
