This set of Aircraft Design Multiple Choice Questions & Answers (MCQs) focuses on “Payload – Weapons Carriage-1”.
1. Typically, Which weapons are utilized for missions?
a) Bombs only
b) High lift device
c) Vortex generator
d) Missile, gun, bombs, etc
View Answer
Explanation: Weapon carriage is one of the important parameters in military aircraft. Traditional and typical weapons are guns, bombs, missiles etc. High lift device is used to generate a higher lift. Vortex generator will generate vortex.
2. Typically, weapons are located near to ___________
a) Aft CG
b) CG of aircraft
c) Fore CG
d) Always at tail section
View Answer
Explanation: Substantial portions of the total aircraft weight are weapons. Typically, weapons are placed near the CG of an aircraft. This would help to make aircraft less influenced by weapons for example, aircraft can perform pitch up when weapon is released and hence, by locating near CG, we can reduce such effects.
3. Which of the following is correct?
a) Bombs are always guided
b) Missile are always free fall
c) Missile can be launched in two ways typically
d) All Missile and bombs adopt similar launching mechanism
View Answer
Explanation: Typically a missile can be launched in two different ways either rail guided or release mechanism. Missiles are not always free fall. They could be rail guided as well. Typically bombs are not guided however some guided bombs are in use as well.
4. Following diagram represents ___________
a) lofting process
b) free falling
c) longerons
d) rail launch system
View Answer
Explanation: Typically missile can be launched in two different ways. Above diagram is showing a typical rail launched mechanism. Rail launcher is typically mounted to the aircraft at either wingtip or a pylon.
5. Following diagram represents ____________
a) typical rail launch
b) typical ejection launch
c) lift Increment method
d) drag reduction design
View Answer
Explanation: In the above diagram a typical ejection launch mechanism for missile is shown. Missile is connected through some hooks which can quickly release the Missile from aircraft. Generally this system is used for larger missiles.
6. Which of the following is a type of weapon carriage?
a) Omni external
b) Uni Conformal
c) Conformal
d) Tail dragger
View Answer
Explanation: Weapon carriage is primarily consideration of military aircraft. Weapon carriage can be of many different types; one of them is conformal weapon carriage system. Tail dragger is landing gear arrangement.
7. All the fighter aircrafts incorporate only external weapon carriage.
a) True
b) False
View Answer
Explanation: Weapon carriage is to be utilized will be decided based on mission profile and requirements of the aircraft. A typical fighter aircraft doesn’t necessarily consist of only external weapon carriage system. It can use combination of various types of weapon carriage systems.
8. Following diagram is showing ______________
a) typical external weapon carriage
b) conformal
c) internal weapon carriage
d) semi submerged
View Answer
Explanation: As shown in the figure, a typical external weapon carriage type is shown. The above diagram is explaining some fundamental principles of an external weapon carriage. As shown in the figure, weapons are located at outside of the aircraft body; mostly below wings as shown.
9. External weapon carriage can suffer from high drag.
a) True
b) False
View Answer
Explanation: In a typical, external weapon carriage weapons are located outside of the aircraft. This arrangement experiences higher values of drag. However, it is most suitable for carrying different weapons.
10. Determine the corrections or otherwise of the following Assertion [A] and Reason [R]:
Assertion [A]: Supersonic flight is very difficult with pylon mounted external weapon carriage.
Reason[R]: External weapon carriage will experience minimum drag at supersonic speeds.
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: External weapon carriage system experiences more drag as compared to other weapon carriage systems. Hence, supersonic flight is virtually impossible for such pylon mounted external weapon carriage. Hence, given assertion is correct however, the reason is false.
11. Following diagram represents _______
a) fully external
b) semisubmerged
c) fully submerged
d) cabin
View Answer
Explanation: In an external system, weapons are located outside of the aircraft body such as at pylon etc. Semisubmerged type is shown in above diagram. Semisubmerged weapons are located partially outside and inside of fuselage as well. This is shown in above diagram.
