Question: 1. The Sikorsky UH-60 Black Hawk helicopter has a 4 bladed rotor with the following specifications Blade mass 113kg (for one blade) . Rotor diameter: 16.36m Rotor speed 258 rpm 1.1 Calculate the mass moment of inertia matrix of the rotor. Take the basis vectors to be aligned with the blades as shown in the figure.

6. The rotor of the Sikorsky UH-60 Black Hawk helicopter has four titanium and fiberglass blades with the following specifications: - Blade mass: 113 kg (each blade) - Rotor diameter: 16.36 m - Rotor angular speed: 258 rpm. (a) Calculate the moment of inertia of the full four-bladed rotor around its center-of-mass (treat the blades as long rods).

The mass of the Sikorsky UH-60 helicopter is 9300 kg. It takes off vertically at t = 0. The pilot advances the throttle so that the upward thrust of its engine (in kN) is given as a function of time in seconds by T=100+2t2.

The mass of the Sikorsky UH-60A helicopter is 9300 kg. It takes off vertically with its rotor exerting a constant upward thrust of 112 KN. Determine how far it has risen when its velocity is 6 m/s.

The mass of the Sikorsky UH-60 helicopter is 9300 kg. It takes off vertically at t = 0. The pilot advances the throttle so that the upward thrust of its engine (in kN) is given as a function of time in seconds by T=100+2(t^2).

The mass of the Sikorsky UH-60 helicopter is 9300 kg. It takes off vertically at t = 0. The pilot advances the throttle so that the upward thrust of its engine (in kN) is given as a function of time in seconds by T=120+2t2. How fast is the helicopter rising after 3s? How high has it risen after 3s?

Question: La masa del helicóptero Sikorsky UH-60 es de 9300 kg. Despega verticalmente en t = 0. El piloto avanza el acelerador de manera que el empuje hacia arriba de su motor (en kN) está dado en función del tiempo en segundos por T=120+2t2. ¿A qué velocidad se eleva el helicóptero después de 3 s? ¿A qué altura ha subido después de 3 s?

Question: (30 pts) The mass of the Sikorsky UH-60A helicopter is 9300 kg. It takes off vertically at time t-0. The pilot advances the throttle so that the upward thrust of it engine is given as a function of time in seconds as T- 100000+2000t where Tis measured in Newtons. 2) A) How fast is the helicopter rising 3 seconds after take off?

A UH60 Black Hawk helicopter is flying at a cruise speed of 278 km/h at standard sea level (SLS) conditions What is the helicopter's cruise Mach number? The helicopter's main rotor is spinning at 320 rpm, what is the Mach number on the tips f the main rotor when it is perpendicular to the helicopter's flight direction? With the main rotor in this

The mass of the Sikorsky UH-60 helicopter is 9300 kg. It takes off vertically at t = 0. The pilot advances the throttle so that the upward thrust of its engine (in kN) is given as a function of time in seconds by T=100+t2. A.) How fast is the helicopter rising 3 s after it takes off? B.) How high has it risen 3 s after it takes off?
