Description

This is a challenging flying model based on the EnerJet 2250 sounding rocket originally produced in 1972. The Trident cluster rocket features a payload bay and offers adventurous rocketeers the whopping lift power of three-motor flights. This rocket can be launched with motors from C to E impulse.

Aerotech F-class motors will fit this rocket, however the extraordinary thrust offered by these motors require a very high build quality and additional strengthening during the build to ensure that the rocket survives the flight. The high altitude achieved during such flights may also necessitate the addition of a stronger nylon or fabric parachute.

This Rocket comes with laser-cut centering rings and fins, plastic nose cone, 24″ nylon parachute, conforming rail lugs, stainless steel welded eye-bolt and E to D spacer to allow C or D powered flights.

This 40.5″ tall rocket should be launched from a rail rather than a launch rod.

Challenges

This is a challenging rocket both to build and fly and therefore not recommended for your first scratch build. The build is not daunting but you should have some experience of building and flying rockets.

During the build you will need to use multiple different glues to maximise the build quality. You should have epoxy, PVA (wood glue) and CA glue available during the build.

Due to the small amount of space available at the rear of this rocket there is not room for motor retention. During launch preparation you will need to friction fit the motors tightly enough that the ejection charge does not blow them out of the rear of the model.

Lighting three motors simultaneously is also, itself, a challenge. Wizard Rockets recommends that you launch this rocket only at club events where other fliers are available to assist in the final preparation and your first launch.

Specifications

Length: 40.5″ (103 cm)
Diameter: 2.22″ (56 mm)
Weight: 11 oz. (315 g)
Motor Mount: 3 x 24 mm.
Recovery System: 24″ Parachute (included)
Projected Max Altitude: 2200 ft. (725 m)

Recommended motors

3 x C, 3 x D or 3 x E motors.

F motors will fit and may be used if exceptional care and attention is taken during the build process to enhance the strength of the rocket. In all cases Wizard Rockets recommends that all rockets are simulated in software (e.g. OpenRocket, Rocksim) to determine the optimum ejection delay and flight profile to assess whether the rocket flight characteristics are acceptable.
