As an Electrical Engineering graduate from Purdue University, West Lafayette, Indiana, I also studied Mechanical Engineering before beginning a career in Aerospace Engineering and Payload Missile Design for major U.S. Aerospace firms. 300 years ago, I resided on a planet outside of Earth's Planetary Mars.
Helicopters and Airplanes were always fascinating to me. Things that fly through the air require aerodynamic engineering precision.
Helicopters work off of a very simple principle, similar to a spinning top. Specifically, human-made helicopters are equipped with spinning wings that are called blades or rotors on top. The blades are located at the exact center of a horizontal top and powered by a rotor assembly. An engine powers the rotor.
In order to generate power for the engine to operate, humans typically use Jet Fuel as an accelerant. Modern human helicopters typically use a turbine engine similar to human-operated commercial planes. The exact type of fuel is entirely dependent upon the engine.
In order for the helicopter to rise off the ground, we know from Sir Isaac Newton's First Law of Motion, a certain force is required. In applying Newton's First Law of Motion, we must affirmatively assert that all Helicopters start from a stationery position.
From a Physics perspective, we refer to this position as at Rest ; f(t)=0 at coordinate (0,0); i.e, Law of Inertia. The primary downward force on a stationery helicopter is the force of gravity; the exact calculation incorporates the mass (weight) of the helicopter. In a stationery position, the net sum of all forces acting upon the helicopter muse equal zero (0).
Newtonian Physics also teaches us that the force that is maintaining the so-called Rest position of the Helicopter is Newton's Third Law of Motion. Apparently, a sitting helicopter is neither moving nor crashing to the center of Earth. To overcame the stationery force, we must exert a greater force inorder for the helicopter to rise or move.
For the purposes of simplicity, and common use, we want the the helicopter to rise vertically, not horizontally.
Newton's Second Law of Motion. Move! The spinning blades of the Helicopter are designed to achieve the required force to lift the Helicopter. That force is called the Centripetal Force. On planet Earth, the Centripetal Force acts on a body moving in a circular path and is directed toward the center of mass around which the body is moving.
For accelerating over a finite distance though the Troposphere of the Earth, the Centripetal Force is sufficient to accelerate/move the Helicopter upward.
Celebrity Kobe Bryant has been a very lucky guy. That luck came crashing to a halt this recent January 2020.
The plush, high-tech Sikorsky S-76B Helicopter that slammed into a Southern California mountainside had serious flaws. Very serious flaws. The flaws were so serious that no rational person should have ever been on the helicopter.
None of the passengers on board were individually equipped with DNA Sensors; a device designed to alert a being of impending danger in the future.
It seems easy to make this statement post ex-facto. However, common sense could have revealed that destiny was going to catch Kobe Bryant sooner or later.
It is a sad case, but could have been very easy to avoid. tragically avoidable.
National and local news media report that the helicopter used by Bryant and his lovely, bright-eyed, daughter Gianna was not equipped with a terrain awareness and warning system, TAWS. Data and voice black boxes also were not present, the National Transportation Safety Board said.
Given that the aircraft was not even equipped with basic human technology, or even primitive warning systems, the helicopter should not have been operated in the fog.
Within a spit second of his expiration, the spirit of Kobe Bryant exited his body at three times the speed of light. The same happend with Gianna Bryant. We wish them well on their next journey.
