3. Exhaust Velocity A jet engine that operates on Brayton cycle is at an altitude (30,000 ft) where the engine entrance temperature is 228 K and the pressure is 30.8 kPa. We also know that the engine compressor pressure ratio is rp= 10 and the fuel to air mass flowrate ratio is 0.03. If the aircraft is moving at a velocity of 305 m/s and uses fuel with LHV 44,102 kJ/kg calculate the engine exhaust velocity. (Note that cp 1.0035...

Quantitative: In the 1950s liquid hydrogen was considered as a fuel for a new type of aircraft being developed, the SR-71 Blackbird (shown in Figure 1). Figure 1: The SR-71 Blackbird Early research on the project focused on which fuel to use for the Blackbird. Pratt & Whitney had a J-57 engine that was designed for kerosene and being considered for implementation on the Blackbird. The J-57 only took 5 months to convert to running on liquid hydrogen, however tests...

Please read the case provided below and answer the following question: In 2007, JetBlue was a booming young airline with a strong reputation for outstanding service. In fact, the low-fare airline referred to itself as a customer service company that just happened to fly planes. But on Valentine's Day 2007, JetBlue was hit by the perfect storm-literally-of events that led to an operational meltdown. One of the most severe storms of the decade covered JetBlue's main hub at New York's...
