01
Start With Physics
Rocket design is constrained by mass, thrust, propellant performance, structural loads, thermal environments, orbital mechanics, and control. Engineering decisions must ultimately close against those physical constraints.
02
Design for Production
A vehicle that is technically capable but difficult to manufacture rapidly cannot support a high flight cadence. Manufacturing therefore becomes part of the system design rather than a downstream activity.
03
Failure as Data
A test failure can reveal previously unknown behavior. The engineering value lies in determining the failure mechanism, modifying the system, and validating that the modification addresses the underlying problem.
04
Optimize the System
Optimizing one subsystem can make the complete vehicle worse. The correct target is whole-system performance: mass, reliability, cost, manufacturing time, refurbishment effort, turnaround time, and mission capability.
