| 41. | The bleed air comes from the engines but is " bled " from the engine upstream of the combustor.
|
| 42. | This air is further compressed by the centrifugal stage, and burned in a reverse-flow annular combustor.
|
| 43. | The blades are responsible for extracting energy from the high temperature, high pressure gas produced by the combustor.
|
| 44. | The glass component has the lowest melting temperature lower than temperatures inside the combustor of a gas turbine engine.
|
| 45. | 855 parts were replaced with 12 3D-printed parts : frames, combustor liners, sumps, rotors.
|
| 46. | Integrated boosters provide a more efficient packaging option, since the booster propellant is cast inside the otherwise empty combustor.
|
| 47. | Ramjets utilize high-speed characteristics of air to literally'ram'air through an inlet diffuser into the combustor.
|
| 48. | At exit from the impeller the air flowed forwards, then turned through 180 degrees to flow rearward through the combustor.
|
| 49. | It carried a passive scramjet engine combustor module as a test-bed for demonstration of air-breathing propulsion technology.
|
| 50. | The D-436 incorporated an updated, higher RPM fan, a lower emissions combustor, and new compressor sections.
