| Note: Note: | The jet engine was started using a two-stroke motor that was housed in the front of the jet engine. A 7.5 kW (10.5 hp) reciprocating engine spun the turbine to starting speed. The starting system was designed by Ing. Norbert Riedel. | The starter system Riedel which consisted of a 10 hp two-stroke flat engine hidden in the intake jet-engine When starting of the jet engine a small piston engine spun up the turbine. | |

Junkers Jumo 004B
The engine formed osemstupňový axiálny kompresorom with diskami and blades zo zliatiny hliníka, group of the compressor so statormi tvorili odliatky of hliníkovej zliatiny in the form of skrutkovaných polovíc. The compressor was stored in the two bearings.
Before predným ložiskom sa nachádzali conversions agregátov poháňaných hriadeľom (čerpadlá fuel, oleja, and the generator) and from preda annexed a small dvojdobý piestový engine Riedler slúžiaci ako štartér. Spaľovacie chamber valcového the shape of boli aj with plamencami zvarené zo žiaruvzdorného sheet. Into each emptied the fuel potrubie with vnútornou nozzle and each mala svoju zapaľovaciu sviečku.
Turbine on spoločnom hriadeli with kompresorom bola stored in two bearings. Matter of fact the turbine wheel bolo steel, the blades so stromčekovým uchytením boli najskôr full of chrómniklovej steel, neskôr sa shaped zo žiaruvzdornej steel and boli hollow. Zaujímavosťou engineand boli threaded skewers vo výstupnej tryske, ktorej pohybom forward or backward sa was optimálny prierez nozzle (optimálny ťah) depending on the nadmorskej výške.
Dĺžka: 3 865 mm
Priemer: 806 mm
Hmotnosť: 720 kg (including agregátov and olejovej tank)
Fuel: Aviation kerosene J 2 or TO 1 (LRX)
Ťah: 8,33 kN pri 8 700 rpm./min. (under's zdrojov of 8.82 kN)
Consumption: vo výške 11 800 m pri rýchlosti 860 km/h pri ťahu 2,54 cn was approximately 580 kg/h; pri country and rýchlosti 900 km/h with ťahom 8,33 kN was approximately 1670 kg/h.
In the after the second svetovej vojne sa in Czechoslovakia vyrábal under the designation M-04 and in Sovietskom zväze under the designation RD-10.
