Probe Separation – Hux I-b

The Hux I-b, a significantly larger design, was quickly put together after the successful Hux I launch. It consisted of a 320kg unmanned probe atop a two-stage rocket with an all-up mass of 10.46 tons and surface TWR of 1.95.

Payload
  • Aerodynamic Nose Cone with TR-2V stack decoupler
  • Probodobodyne OKTO2 + 2 Z-100 Rechargable Battery Packs, Communotron 16 deployable antenna and a dipole antenna
  • Oscar-B fuel tank
  • Hux I-b on launch padLV-1 liquid fuel engine
Second stage
  • TR-2V stack decoupler
  • NCS Adapter + 2 dipole antennas
  • Advanced S.A.S. Module + 4 RV-105 RCS thruster blocks
  • FL-R25 RCS fuel tank
  • FL-T400 fuel tank
  • LV-909 liquid fuel engine
First stage
  • TR-18A stack decoupler
  • Advanced S.A.S. Module (didn’t really need a second one of these)
  • FL-T800 fuel tank + 4 Delta-Deluxe winglets
  • LV-T45 liquid engine

Hux I-b first stage separationThe LV-T45 is slightly heavier and not as powerful as the LV-T30 engine however it is a gimballing engineĀ and I wanted to experiment with it. In hindsight it wasn’t really necessary as the first stage was equipped with winglets for aerodynamic control and it was spent and jettisoned well before they would lose effect. The upcoming Hux I-c mission however will be using the same design as this launch so it was decided to keep themĀ similar.

Hux I-b second stage separationWith the Hux probe reaching a respectable altitude of 29,998m the launch was considered a successful test of a basic multi-stage that will be used for orbital insertion. The mission lasted 5m01s with the probe impacting the ocean 65km from the KSC.

Kerbin’s atmosphere extends to roughly 69,078m so I’ve got a fair bit to go to escape the atmospheric drag and make it to orbit. The next mission will be an attempt at getting this basic probe to Low Kerbin Orbit.
