Unit 15 Aircraft Propulsion Technology Outcome 1.1 1) T=m(V0 -V1) m= 1000kg/s T=1000(120-100) V0 =120m/s T=20,000N V1 =100 m/s 2) Total thrust =Thrust of core engine + thrust of fan Thrust = Mass airflow x (bypass velocity – aircraft velocity) + Mass airflow x (exhaust velocity – aircraft velocity) Thrust = 300 x (180-120) + 200 x (220-120) = 300 x 60 + 200 x100 = 1800 + 2000 = 38,000N 3) Cross reference to Unit 17 Gas turbine science outcome

feet per minute at the compressor inlet 3. Use the Brake Horsepower for a Generic Centrifugal Compressor graph to determine the basic brake horsepower. 4. Calculate the actual power by multiplying the basic brake horsepower by the ratio of the inlet pressure (in psig) to 14.5. This will give actual power in units of horsepower. You may wish to convert it to watts. 5. Calculate the actual specific work by dividing the actual power (in W) by the mass flow rate (in kg). 6. Calculate the actual adiabatic

In short, leaders who are more empathic are better able to reach the fulcrum of their followers’ judgment. Perhaps the most obvious is having the courage of our convictions, especially in the face of pressure from others. The lead character – played by Henry Fonda – is under significant pressure form his fellow jurors, but he is determined to explore all of the evidence before he reaches a conclusion. He chooses principles over expediency. Important decisions should be given time. In the movie

An Ethical Dilemma (Chapter 6) Lael Mathews has to decide between three different people to promote to manager. One is a thirty-four year old African American female, one is a fifty-seven year old Caucasian man, and the third one is a twenty-seven year old Asian American. They all have three different situations and problems of their own. Lael Mathews know each ones background which makes it even harder to make a decision as to which one deserves and will best fit the position. Liz is the thirty

Subject: Converging-diverging nozzle experiment In this experiment, we used manometers to measure the pressures in the nozzle relative to atmospheric pressure. A water manometer is connected to the inlet pressure tap (P0-P1) and also connected to the throat (P0-P2) and downstream (P0-P3) pressure taps as well. To start this lab we adjusted the flow rate to increase (P0-P3) in equal steps of 2.5 inches of water until the nozzle is choked, which means there is no further increases in (P0-P2) and

Airbags are safety features that are designed to save passengers from harm in a head-on collision. Airbags react within milliseconds of a crash, and the folded nylon bag quickly becomes inflated with nitrogen gas. The inflated airbag has the role of being a cushion for passengers and prevents them from hitting into the steering column and dashboard, which can cause painful injuries for passengers. Airbags were invented by John Hetrick in 1953 after Hetrick, his wife and young daughter got

Boyle's Law Examples in Real Life Boyle's Law Explained In 1662, Robert Boyle discovered that when held at a constant temperature, the volume and pressure of a gas are inversely proportionate. Put simply, when the volume goes up, pressure drops, and vice versa. The mathematic equation is equally as simple: PV=K where P=Pressure, V=Volume, and K is simply a constant. This has become a basic principle in chemistry, now called "Boyle's law" and is included as a special case into the more general
