This set of Aircraft Design Multiple Choice Questions & Answers (MCQs) focuses on “Payload – Weapons Carriage-2”.
1. Following diagram represents ____________
a) conformal
b) internal weapon carriage
c) external weapon carriage
d) fully submerged
View Answer
Explanation: A typical conformal weapon carriage system is shown in the figure. As shown in the above diagram, weapons are mounted at the bottom of the fuselage. This reduces drag generated by weapons as compared to the external weapon carriage.
2. Following diagram represents __________
a) conformal
b) non submerged weapon carriage
c) external weapon carriage
d) internal weapon carriage
View Answer
Explanation: An internal weapon carriage system is presented in the above diagram. As shown in the figure, weapons are located inside the aircraft itself. This helps to reduce the drag tremendously. Drag produced by internal weapon carriage is lowest among all 4 types of weapon carriage.
3. Following diagram represents __________
a) rocket system
b) missile layout
c) typical gun
d) missile launch system
View Answer
Explanation: Gun is one of the most common and important weapons used in military aircraft. The above diagram is showing typical gun viewed from side. Gun should be located based on mission requirements. Ammunition container is typically located at aft end of the gun as shown.
4. Which weapon carriage option gives more flexibility to carry different weapons?
a) Internal carriage
b) External carriage
c) Conformal
d) Rail launch system always
View Answer
Explanation: External weapon carriage system provides more flexibility to carry different weapons. This is one of the advantages of an external type weapon carriage.
5. If weapon is mounted at bottom of the fuselage then it is called __________
a) internal carriage
b) external always
c) conformal
d) rail launch system always
View Answer
Explanation: When weapons are mounted at bottom of fuselage then, it is termed as conformal type of weapon carriage. Drag produced by conformal is lower than external but higher than the internal weapon carriage system.
6. Which of the following is a disadvantage of semi-submerged weapon carriage?
a) Indentation will increase structural weight in this type of weapon carriage
b) Lowest possible weight
c) Drag will be more than external carriage
d) Drag will be lower than that of the external carriage
View Answer
Explanation: Semisubmerged type of weapon carriage will reduce drag and have a lesser than of the external weapon carriage. Semisubmerged type will increase structural weight sure to indentations in aircraft.
7. Which of the following will produce the lowest drag?
a) External always
b) Internal carriage
c) Conformal
d) Rail launch system always
View Answer
Explanation: External weapon carriage system is known to produce the highest drag. Conformal system reduces drag at some extent. Drag produced by semi submerged falls between conformal and internal. An internal weapon carriage system will provide least drag among all mentioned options.
8. Following diagram represents ____________
a) rotary weapons bay
b) linear motion
c) cabin
d) cockpit
View Answer
Explanation: Rotary weapons bay is a special type of internal weapon carriage system. A typical rotary weapons bay is shown in diagram. This arrangement can be used to launch all of the weapons through single door.
9. Gun should be located near to the centerline of aircraft.
a) True
b) False
View Answer
Explanation: When gun is fired, it tends to generate recoil force. An air to air gun such as M61A1 produces recoil force about 2 or more tons. This can produce sudden yaw and to prevent or to reduce such effects, we should locate gun near to aircraft center line.
10. Determine the corrections or otherwise of the following Assertion [A] and Reason [R]:
Assertion [A]: Typically, gun should be located away from the cockpit.
Reason [R]: Gun can induce sudden yawing.
a) Both [A] and [R] are true and [R] is the correct reason for [A]
b) Both [A] and [R] are true but [R] is not the correct reason for [A]
c) [A] is true but [R] is false
d) [A] is false but [R] is true
View Answer
Explanation: when we fire a gun, it produces bright flash. Large smoke cloud will be produced when we fire a gun. Hence, a gun should be located in such way that the smoke do not block vision of pilot. Larger gun will generate more recoil force which can produce sudden yawing.
11. Which of the following is an advantage of internal weapon carriage?
a) RCS is more than conformal
b) Highest possible RCS
c) RCS is more than external
d) Weapon RCS will tend to be none
View Answer
Explanation: An internal weapon carriage system hides weapon from radar detection. This is due to fact that weapons are located inside the aircraft itself in an internal weapon carriage system. Conformal configuration has more RCS than internal weapon carriage system.
