Weike-2 Launch Success and Fuel Testing¶

Test Location: Unspecified (presumed to be the test site)
Participants: Principal Zhou, Principal Zhao, Principal Yang, VHSTIT team members
Recording Time Range: January 8, 2026 (Friday) 13:00 - 16:30 (Beijing Time)
Log Compilation Time: January 9, 2026

Serial No.	Rocket Model	Fuel Type	Executor	Result	Notes
1	Weike-1	Fuel Type 2	Principal Zhou	Ignition failure	First attempt
2	Weike-1	Fuel Type 2	Principal Zhou	Ignition failure	Second attempt
3	Weike-1	Fuel Type 2	Principal Zhou	Ignition failure	Third attempt
4	Weike-2	Fuel Type 1	Principal Zhou	Ignition successful, flight altitude 10.73m	Presumed overweight nose cone causing insufficient altitude
5	Weike-1	Fuel Type 1	Principal Zhao	Ignition successful, flight altitude 59.63m¹	Altitude sensor detached, parachute did not deploy

Insufficient reliability of Fuel Type 2: Three ignition failures, possibly related to the uniformity or combustion characteristics of self-made fuel.
Structural design defects:
Overweight nose cone (Weike-2) leading to limited flight altitude.
Nose cone wrapping too tight (Weike-1) affecting parachute release.
Data recovery mechanism: Sensor fixing method needs improvement to avoid detachment.

Suspend use of Fuel Type 2, prioritize testing prefabricated fuel (Fuel Type 1).
Optimize nose cone weight balance and front structure to reduce front-end mass.
Improve parachute compartment design to ensure deployment mechanism is not obstructed by wrapping.
Strengthen sensor fixing method, employ redundant fixing or cushioned design.

Note: Except for explicitly stated times, some times are estimated; all analyses are based on current test data and require further verification.
