6 d$ ]3 a" M1 q$ Amusk 的 electric compressor fan 在其计划书里是这么描述 （其中的一种）：
G' ]2 m! W/ g, T- M% g5 ?- e) O& @0 z
Hyperloop Passenger Capsule
% u( K6 A' A! n {) @2 x( m1 c a1. Tube air is compressed with a compression ratio of 20:1 via an axial compressor. . m! _( \- {" F' S
2. Up to 60% of this air is bypassed: / r( k5 a! G1 l9 t0 `% B
a. The air travels via a narrow tube near bottom of the capsule to the tail. 0 y. c& h4 S) A6 p2 y
b. A nozzle at the tail expands the flow generating thrust to mitigate some of the small amounts of aerodynamic and bearing drag. % _; T9 K# q5 A# x; 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.
: {/ r* e, i9 ]5 i& ^% ra. This air is stored in onboard composite overwrap pressure vessels.
3 ?- r! R+ ?. N6 L# H+ W6 vb. The stored air is eventually consumed by the air bearings to maintain distance between the capsule and tube walls.
4 ~+ \# S6 Q% |. a5 I9 h2 l- f( ?4. An onboard water tank is used for cooling of the air.
% I) T- N5 h _" S, ]0 H& Ka. Water is pumped at 0.30 lb/s (0.14 kg/s) through two intercoolers (639 lb or 290 kg total mass of coolant). & D5 o3 p3 G+ g$ l, s5 Z1 I8 w7 X
b. The steam is stored onboard until reaching the station.
; P/ }7 \. b* nc. Water and steam tanks are changed automatically at each stop.
$ U1 l2 m& j! }4 s/ @' y% z5 Z- O5. The compressor is powered by a 436 hp (325 kW) onboard electric motor: 6 N4 V5 k& J) H( _1 ]# T; N( `. O
a. The motor has an estimated mass of 372 lb (169 kg), which includes power electronics. 0 M% {# \, J: h9 ~; \, d' E
b. 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.
8 c# {- @5 M- Bc. Onboard batteries are changed at each stop and charged at the stations. |
