8) simple and sound:
airframe: Me-163D, slightly modified to accomodate the
engine: HeS30, a lightweighted axial jet engine designed by Adolph Müller, which weighted 2.2 times the weight of the HWK 509 rocket engine but only half the weight of a Jumo-004B. This weight increase may be offsetted by fewer fuel capacity as the specific fuel consumption of the HWK is horrific in comparison to the HeS30.
dates for HeS30:
date of design: 1940
date of benchtests: 1942
date of service: never
ordering background: proposal for a class I-turbine (alike Jumo-004 and BMW-003), later rejected
because of avaiablity of Jumo and BMW-engines in this powerclass.....One of the few WRONG decisions the RLM did in jet propulsion.
compressor: 5 stage axial
turbine: 1 stage axial
weight (dry): 390 Kg (860 lbs) (for comparison: Jumo004: 730 Kg; BMW 003: 540 Kg)
Note that the construction of this engine was simplier than the Jumo but more difficult than the BMW.
compression ratio: 1:3
poweroutput: 860 Kp nominal (1896 lbs)
poweroutput enforced: 910 Kp benchtested (2006 lbs)
poweroutput designed: 1125 Kp (2480lbs) at 10500 rpm (for comparison: Jumo-004: 840-890Kp; BMW-003: 800Kp-927Kp enforced)
thrust to weight ratio: 2.205-2.333
This engine was unexceeded in the following aspects until the early 50´s:
-lowest frontal area
-lowest specific fuel consumption
-highest thrust- weight ratio
and now You have a nightmare fighter and a dream to fly...
