# U$ B2 D; K. J k& D/ omusk 的 electric compressor fan 在其计划书里是这么描述 （其中的一种）：6 `% F0 O3 @: o# ~5 q3 n* ~) ^9 W# H
- j2 e ]* a2 X' U& KHyperloop Passenger Capsule
0 z! q8 o8 s0 B1 f. C5 y3 X. ]1. Tube air is compressed with a compression ratio of 20:1 via an axial compressor. r& h6 s/ C. C6 l9 ^, Y
2. Up to 60% of this air is bypassed: 6 ?9 l; n0 R/ f) r1 J
a. The air travels via a narrow tube near bottom of the capsule to the tail.
8 G0 r$ p8 y; @; S5 ]: R4 D0 Rb. A nozzle at the tail expands the flow generating thrust to mitigate some of the small amounts of aerodynamic and bearing drag. 6 Z8 b5 H% C, ?( q0 `( X
3. Up to 0.44 lb/s (0.2 kg/s) of air is cooled and compressed an additional 5.2:1 for the passenger version with additional cooling afterward. , m ]4 t$ R! V/ ]( l: u+ c+ m
a. This air is stored in onboard composite overwrap pressure vessels.
+ y' J0 b6 K- ]( ~9 ~: |b. The stored air is eventually consumed by the air bearings to maintain distance between the capsule and tube walls. 7 U: [5 }5 E) U. C, b
4. An onboard water tank is used for cooling of the air.
$ n) s4 D b2 e/ `a. Water is pumped at 0.30 lb/s (0.14 kg/s) through two intercoolers (639 lb or 290 kg total mass of coolant).
2 ?8 [: G2 }" H- Vb. The steam is stored onboard until reaching the station. x# U2 E" I9 y f
c. Water and steam tanks are changed automatically at each stop. + o6 [( f/ `5 ], g
5. The compressor is powered by a 436 hp (325 kW) onboard electric motor:
4 R7 R# y6 L5 S6 i4 }- m5 ?$ oa. The motor has an estimated mass of 372 lb (169 kg), which includes power electronics.
0 E! o5 D/ |) J2 hb. An estimated 3,400 lb (1,500 kg) of batteries provides 45 minutes of onboard compressor power, which is more than sufficient for the travel time with added reserve backup power.
S: w0 V1 _5 @c. Onboard batteries are changed at each stop and charged at the stations. |
