Kyte X3
Don't just predict energy.
Use it intelligently.

Once we can predict endurance, the next question is whether the aircraft can change how it flies to extend the useful endurance it has.

CHAPTER 01
— Six optimization levers

The degrees of freedom
an aircraft actually has.

An aircraft is not a fixed thing flying a fixed plan. It is a system with six real decisions it can make continuously. Kyte X3 exists to study which decisions actually earn more useful flight time.

FIG. 01 · Six levers · What the aircraft can actually change CONTROL SURFACE
Lever 01
Adaptive airspeed

Fly the airspeed that minimizes energy for the current wind and mission — not a fixed cruise number.

Lever 02
Mission replanning

Rewrite the flight plan mid-flight when the energy budget disagrees with the original plan.

Lever 03
Wind-aware flight

Use the estimated wind field to choose the route and altitude that spends the fewest joules.

Lever 04
Energy-aware route

Route selection driven by predicted energy cost, not just distance on a map.

Lever 05
Solar-assisted energy

A second, environmental energy source — with real trade-offs to characterize honestly.

Lever 06
Payload-aware decisions

Mission decisions shaped by current mass and how it affects predicted endurance.

CHAPTER 02
— Transition to SolarWing

Sunlight becomes
a new variable.

Add solar energy to the aircraft and the fundamental question changes. It is no longer "how fast is the battery draining?" — it is "which side of the beam wins right now?"

Energy-balance scale diagram: a copper glowing sun labeled P_solar on the left pan, three consumers (propeller, avionics, losses) on the right pan, tilted toward solar. Beneath is the equation dE_bat/dt = P_solar − (P_prop + P_avionics + P_loss).

— Battery energy rate
dEbat/dt = Psolar − Pprop − Pavionics − Ploss

The battery gains when solar exceeds total power draw. Every optimization lever in Chapter 01 can shift the sign of that number — pulling more energy in, or paying less energy out.

CHAPTER 03
— Research questions

Questions Kyte X3 is designed to attack.

Five open engineering questions grow out of the six levers and the solar equation. The purpose of Kyte X3 is not to guess at answers — it is to build the aircraft that can measure them.

Question-tree diagram: solar-wing aircraft at the bottom with five copper question branches sprouting upward, each labeled with one of the research questions.
FIG. 03 · Five open questions · The aircraft is the instrument TO ANSWER · NOT ASSUME
01

When does solar energy meaningfully improve endurance?

02

When does added solar-panel mass cancel the benefit?

03

Should an aircraft climb when surplus solar power exists?

04

How should the aircraft respond to changing sunlight?

05

Does adaptive airspeed beat fixed-airspeed on real missions?

— The purpose of X3

Kyte X3 does not know the answers. Kyte X3 is how we find out.

Optimize is a discipline.
Understand-itself is the leap.
