Final answer:
The question relates to the specific design features of a UH-60M Main Rotor Blade in helicopters, including the use of a graphite epoxy spar, the chord dimensions, and the angles of the anhedral tip, static twist, and swept-back blade tips. This is an Engineering topic that would be covered at the College level.
Step-by-step explanation:
The question asks about specific details of the UH-60M Main Rotor Blade Design used in helicopters. This type of question falls under the category of Engineering because it requires knowledge of aeronautical design principles and the physics of helicopter flight. For the rotor blade characteristics mentioned, the graphite epoxy spar provides structural support due to its high strength-to-weight ratio. The chord of the blade relates to the cross-sectional width of the blade at its widest point. The 20-degree anhedral tip design is likely implemented to improve aerodynamic stability, and the 16.3-degree static twist helps to ensure more uniform lift distribution across the blade's length. The blade tips being swept back 30 degrees is another aerodynamic feature that can reduce noise and vibration at high speeds.
In practice, rotor blades are complex structures that have to endure various forces such as lift, drag, and centripetal accelerations, especially at the tip. This question would likely be encountered in a College-level course, perhaps within an Aerospace Engineering program, where students study the mechanics and design elements of aircraft and rotorcraft.
