PUSHING THE LIMITS OF THE ROCKET EQUATION

For the human race to become a space civilization, space travel should become easier, much like getting on an airplane to go to the cities nearby.
To do so, rockets should become far more efficient than now.


Many technical problems out there are yet to be solved. The vehicle should be reusable without any major refurbishment between flights. Engines should be more reliable yet more efficient. Structures must withstand both fierce heat of reentry and extremely low temperature of propellant for thousands of times but should still be extremely lightweight. Flight control system should be smarter to handle more complex manuvers.


Everyone at Perigee is dedicated to solving these problems. Together, we are changing the way people view the spaceflight.

LEADERSHIP
Founder & CEO
YOON SHIN 😎

Yoon Shin is the founder and the CEO of Perigee, as well as the chairman of the board.

Yoon is responsible for all sales and system developments at Perigee, particularly overseeing critical decisions in the launch vehicle development program.  He is also an engineer who is directly involved in the company's major design process. In his "engineer mode," Yoon designed the initial layout of the 3-ton turbopump and the thrust chamber of the BW1 second stage engine.

Yoon envisions the future of humanity in exploring the unknown worlds and wants to be a part of that journey. He was born in 1997 when the film Contact was released. When he watched the film as a teenager, he was immediately captivated by it and decided to become an HAM operator. If you hear DS3PWS on air, please say hello. He is also an active amateur astronomer. During his university years, he ground a mirror and built an 8-inch reflecting telescope. He also crafted an equatorial mount for astrophotography.

Yoon is a Master's Student in Aerospace Engineering at KAIST (Korea Advanced Institute of Science and Technology), where he earned a Bachelor of Science degree in the same department.

As a propulsion engineer, he established the design rule of the pintle injectors and cooling channels for the combustors used in Perigee's methane engines. The design concept of Blue 1S and Skyblue are his own works as well, from flow schematics and component layouts, all the way down to the ignition sequences.

EK's expertise in propulsion system design extends from chemical to ion propulsion. Before joining Perigee, EK worked at the earth observation satellite manufacturer, Satrec Initiative, where he was responsible for the development of ion thrusters and their feed units.

A distinguished graduate of KAIST, EK holds both a Master's and Bachelor of Science degree in Aerospace Engineering.

VP Flight Control
SEBUM CHUN, PH.D. 🧭

Dr. Sebum Chun is the Vice President of Flight Control at Perigee, reporting to CEO Yoon Shin. SB is responsible for the design decisions for Perigee's flight control hardware, software, and GNC algorithms.
