<p>
The N-3.5 rocket has similar specifications to the previous N-3 rocket.
However, much redesign and reinforcement were made to improve the performance.
</p>
<p>
Remarkable upgrades were made to the casing of the solid rocket motor,
the joint section between the solid rocket motor and airframe,
and the parachute ejection mechanism using pyrotechnics.
All those components were successfully evaluated through several ground tests before the actual flight.
</p>
<p>
The N-3.5 rocket was the Nakuja's first high-power rocket to achieve an apogee greater than 1,000 m during the test flight.

The N-3 rocket improves on several issues experienced with the N-2 rocket,
including a parachute with improved reliability, on-board flight logging,
and a comprehensive redesign of the airframe and launch pad.
</p>
<p>
The solid rocket motor uses KNSB, as on the N-2 rocket,
and the apogee has been upgraded to 1,600 meters.

<p>The N-2 rocket aims to bring the payload up to 500m altitudes. The
casing and the nozzle of the solid rocket motor are made with mild steel, and the fuselage is made with the
fiberglass. It will demonstrate the performance of the flight controller to stabilize the rocket
using reaction wheel and active canard fins. The payload camera records the video during flight. The payload
is recovered by a parachute and telemetry system using GPS.</p>
<p>Due to the higher apogee, the launch was conducted based on the assistance from the Kenya Space Agency (KSA).</p>

<p>N-1 rocket is our first rocket powered by a solid rocket motor that uses sugar and potassium nitrate
as
the propellant. The airframe is 3D printed and equips the minimum required flight electronics. Through
the
development of the N-1 rocket, we aimed to acquire basic rocketry techniques and establish a safety
launch
sequence.</p>
