nanoAlt - updated product line

Earlier this week I wrote a blog detailing the planned product line of the revamped nanoAlt architecture.  In this post I'm going to update my plans on that and introduce some new additions.

In terms of the previous blog post, nanoAlts Alpha and Bravo are unchanged and will be released as described.  nanoAlt Alpha will purely be peak detection and feedback on recovery, while nanoAlt Bravo will include the addition of a pyro channel, configured to fire either as a timer after apogee or at a set height above launch (or a height as a proportional value of the apogee with a minimum for safety, haven't worked out the best case yet).

nanoAlt Charlie was a provisional model that included a small built in pyro charge for use in very small minimum diameter rockets.  The idea would be to create an extremely mass efficient package for a separate pyro deployment charge in A-C impulse class rockets.  Research into pyro handling, characterisation, as well as making the charge work with the rest of the nanoAlt design, and issues with shipping it internationally, have resulted in the nanoAlt Charlie model being iced.

Replacing nanoAlt Charlie, with release dates TBA, are two new models-

  • nanoAlt Delta - this model will include support for dual deployment parachute architectures, either with two pyro channels, or a parachute release setup designed to implement 2-stage parachute designs.
  • nanoAlt Echo - this model will build on the design of nanoAlt Delta by including more telemetry gathering and a downlink via hobbyist radio frequencies.

Work on Delta and Echo will begin after the release of Alpha, Bravo, and Integrate.

I'm also in the process of gathering data about commonly used body tube and coupler inner diameters for reference in the design of nanoAlt Integrate.  This will be a 3D printed framework designed to secure the altimeter in various sized rockets.  The larger the rocket, the more models Integrate will support.  At the moment I'm looking at different sized models up to potentially 38mm (or associated coupler inner diameter, if that's easier for people) and for sizes above that a more adaptive Integrate will potentially be designed to be flexible across high power rocketry sized electronic bays.

Around the release of Delta/Echo, I'll also look at a revision 2 of Alpha and Bravo, potentially with a method of reading out more detailed flight data instead of just the peak altitude.  Watch this space!
