Background

The mission of PlanetSpace is to make space travel accessible to the general public. The company has focused its main efforts on two major projects; the Canadian Arrow which is in development, and the Silver Dart which is a proposed orbital spaceplane. The Canadian Arrow is a privately funded rocket and space travel project founded by London, Ontario, Canada entrepreneur Geoff Sheerin. ... A spaceplane is a rocket plane designed to pass the edge of space. ...

Canadian Arrow

The Canadian Arrow is a 16.5 m tall two-stage rocket, where the second stage is a three-person space capsule. Their somewhat conservative approach has been to base the design of their rocket engine and aerodynamics on the well proven V-2 design from WWII. German test launch. ...

First stage

The first stage is 10.2 m long and 1.7 m in diameter. It is propelled by a single liquid fuel rocket engine. It produces a thrust of 254 kN. Graphite jet vanes are used for stabilisation before the rocket has reached a velocity high enough for the four fins to be effectual. In about a minute after ignition, the fuel is depleted and the engine shuts off. The kilonewton, symbol kN, is an SI unit of force. ...

Second stage

The second stage is 6 m long and 1.7 m in diameter at the base. It carries the three astronauts and is propelled by four JATO-type solid rocket engines. These are ignited immediately after stage separation, and will carry the capsule to an altitude of ~112 km. Cold gas jets are used for attitude control. JATO is an acronym for Jet Assisted Take Off. ...

Crew Cabin Escape System

The four solid rocket engines in the second stage can be fired at any time, including when the rocket still stands on the launch pad. This allows an escape system, which can, in a case of an emergency, quickly separate the second stage from the rocket and propel it to an altitude of 1.5 km, where the parachutes can be deployed.

Rocket engine

The rocket engine uses alcohol and liquid oxygen as propellants, and produces a maximum thrust of 254 kN, and burns for 55 s. It is constructed of low carbon steel, with propellant injectors made out of brass. The kilonewton, symbol kN, is an SI unit of force. ... Brass is the term used for alloys of copper and zinc in a solid solution. ...

Flight profile

The Canadian Arrow rocket will launch vertically from the ground. Initial thrust is ~75.5 kN, but the rocket quickly reaches maximum thrust. After 55 s, the propellant is depleted and stage separation occurs. The solid fuel rockets in the second stage are ignited and boosts it up to an altitude of ~112 km, where the crew and passengers will experience a few minutes of zero-G.

After stage separation the first stage reaches an apogee of over 80 km before descent begins. Four parachutes slows it down before splashdown occurs at a speed of ~9 m/s, after which recovery of the stage can take place.

At descent, the crew cabin (the second stage) will use a ballute to reduce the speed. When it is slowed down to subsonic speed, the ballute is released and pulls out the three parachutes for the splashdown. A ballute (a compound word combining balloon and parachute) is a device that has been proposed for use in spacecraft aerobraking. ...

Silver Dart

Based on the U.S. Air Force's Flight Dynamics Laboratory-7 (FDL-7) program, the Silver Dart is a lifting body designed to glide from hypersonic speeds of Mach 22 down to landing. The goal is to develop an orbital space craft/hypersonic glider capable of carrying around eight passengers. The spacecraft is expected to launch vertical atop a stack of about 10 Canadian Arrow rocket engines and land horizontally on an aircraft runway, they added. The United States Air Force (USAF) is the aerospace branch of the United States armed forces. ... The lifting body is an aircraft configuration where the body itself produces lift. ... In aerodynamics, hypersonic speeds are speeds that are highly supersonic. ...

NASA based its X-24B test aircraft on the FDL-7 lifting body and valued the added range and stability the sleek, sharp-nosed design. FDL-7's lifting body design would also give the Silver Dart about twice the lift coefficient as NASA's space shuttles at subsonic speeds.
