PML offers a number of items relating to multi-staged rockets. First, we offer
two-stage rocket kits, such as the Thunder ‘n’ Lightning, Quantum Leap II and
Quantum Leap 3000. We also offer Interstage Coupler systems, and igniters to use
with staging timers to ignite the upper stage motor.
Interstage Couplers are used to house staging timers and to connect the upper and
lower stages together. The Interstage 3000, the latest version from PML, is used in
our two-stage rocket kits, but is now available for scratchbuilders designing their
own staged rockets. Using an IS3000 system from PML is a quick, simple solution
to an often-difficult design problem. Interstage 3000 kits are ready to ship in 2.1,
2.5, 3.0 and 3.9" diameters.
To use an IS-3000 system, the booster needs 3" (regardless of diameter) at the top,
just like a regular rocket would for a payload coupler or nosecone shoulder. The
sustainer (upper stage) also requires 3" clear at the bottom. Click here for a PDF
file that illustrates design requirements for the upper stage. Click here for a file that
shows design requirements for the Terrier IS3000.
