SP-1 Sharp Shinned: Solar Glider Concept

The SP‑1 "Sharp Shinned" is our experimental concept for an ultralight, solar‑assisted flying wing inspired by the YF‑23 and modern solar glider technologies. Designed to maximize solar power-to-weight ratios with a diamond wing geometry for optimal lift and solar surface area.

Author's note: Images generated were made in the early days of AI image generation. Im keeping this here partly for historical records, but more importantly to showcase where AI is great (math and spec sheet lookup) vs where it stuggles (render a YF-23 based on an image of said YF-23, from wikipedia.)

Project Overview

Solar Glider Concept

Mission Overview

The SP-1 is designed as an ultralight solar-assisted flying wing leveraging modern solar technologies for extended endurance. This isn't a weather reconnaissance jet — it's a sustainable flight platform focused on maximizing solar energy capture with minimal weight.

Key focus: Solar power-to-weight ratios, diamond wing geometry, and dual-seat ultralight operation with glider-level wing loading.
