The Concept

The Orizon is a business jet equipped with a variable-inlet, air breathing engine that could take off from the tarmac, cruise between Mach 3 and 5, and then fly all the way up into space by using onboard oxidizers with DASS GNX engines. It will approach towards Mach 25 in space.

The Background

Business jets will turn 60 this September. The Lockheed JetStar was the first to fly in 1957, and this industry will continue to progress like any other industry. How? I like the idea of supersonic vehicles, but what about a single stage to orbit jet (SSTO) that could bring you into space? The Orizon as it turns out would be designed to carry its passengers directly into low earth orbit.

How It Works

The Orizon would be able to take off directly from a 6000-foot runway using three DASS GNX Engines from Space Engine Systems. These engines would probably be the most environmentally friendly engines [based on nautical mile travelled] and possibly the most reliable reusable engine on the market.  Space Engine Systems is an air breathing engine manufacturer of supersonic and hypersonic engines for aerospace and space applications.

In aerospace terms, it could potentially take you anywhere on earth within 4 1/2 hours at full speed. The air-breathing engines would provide enough power to lift off and climb to 30 kms altitude at Mach 5, and then exit to space and land back on earth. In short, it could be built to handle aerospace DASS GN1 and space combined with DASS GNX engines.

Even using DASS GN1, the pilot could climb to 100,000 feet, where passengers could see Earth’s curvature. Therefore the Orizon could be also be used as space tourism vehicle.

The Orizon has a blended wing body shape with one long leading edge. Passengers would sit in a large, boardroom-like cabin, which could be configured to seat up to 20 passengers or replicate any type of business architecture. The galley and baggage compartments are aft.

What It’s Used For

The Orizon would be developed to carry its passengers at supersonic speed anywhere around the world and even into space. It could be used to fly tourists to inflatable space hotels located in low earth orbit. Maybe even one day it could be engineered to travel and land on the moon.

Of course, we are long way from such a full scale vehicle. The DASS GNX engine project is fully funded and is going to full scale testing in 2018 and for commercialization by 2020. All lab scale studies have been completed. The air breathing engine has more than 3.5 times specific impulse than a regular rocket engine. This saves on fuel and storage reducing mass to achieve escape velocity. The energy required to achieve escape velocity is tremendous, so the Orizon’s layout will need to be structured to hold the required fuel and its shape will evolve based on all the features and performance objectives required by its customers.

The promoters of the DASS GN1 engine and DASS GNX is Space Engine Systems Inc. spear headed by Pradeep Dass, President & CTO. He is a mechanical engineer with various high technology disruptive technologies and business including Aerospace/Space applications.

The Orizon concept was imagined in December 2016 by Charles Bombardier and designed by Ashish Thulkar, an Industrial Designer from Bangalore, India. Ashish graduated with a master’s degree in design from the Indian Institute of Science in 2014. He currently works as a freelance vehicle designer in India. He also created the Drone Tower concept and the Tridika people mover.
