Korean Hypersonic ALCM (Baby-Kinzhal?) w/ Aerospace SIM

  [See Previous Contents]

Aerodynamics Series

  I had modeled SCRamjet missile expected to be integrated to KF-21. Weight is limited to 3,000lb to fit KF-21's pylon limit. See the detailed result below. 

SUMMARY

Modeled (with some assumed value) Baby-Kinzhal (Kh-47M2) w/ SCRamjet is analyzed. 

- Solid booster rocket 600kg w/ 260 ISP

- SCRamjet fuel 50kg w/ 900 ISP

In order to achieve Mach 5 cruise speed, most of fuel is used for Boost phase. 

3000lb class ALCM shows about 900km range w/ Mach 5 cruise speed. 

- it is reduced to 600km when ground-launch.

- it is reduced to 330km when only rocket is used for same flight profile.

  (it is similar to Kh-15 Kickback class missile)

If missile is launched at ground, range is reduced to 670km.

- but Mach number variation is severe at Cruise Altitude. 

- 0.6t Booster should be used to match Air-Launch profile.
