Guidance and Fuzing Systems Flashcards
What are the three main phases of the Detect-to-Engage sequence?
Boost, Midcourse, Terminal
What is the primary function of the boost phase in a missile’s flight?
To bring the missile to stable flight and toward the target, often assisted by a booster component.
During which phase of missile flight are inputs most commonly required to keep it on course?
Midcourse phase
What are the three main types of guidance systems?
Command guidance, self-contained guidance, and homing guidance.
How does semi-active homing guidance work?
The missile carries a receiver, while an external source (e.g., ship or aircraft) illuminates the target.
What type of homing guidance is known as “fire and forget”?
Active homing and passive homing.
What are the three major components of a fuze?
Safing & Arming (S&A) Device, Target Detection Device (TDD), and Detonator.
Which type of proximity fuze is commonly used in torpedoes and mines?
Acoustic, pressure, and magnetic fuzes.
Why are safing & arming devices arranged in series while detonators and target sensors are arranged in parallel?
Series arrangement ensures safety (if one device fails, the system does not arm); parallel arrangement ensures reliability (if one device fails, an alternative path is available).
