What We Do: 

What We Do Frontier Astronautics is a mild-mannered subcontractor, supplying the burgeoning Entrepreneurial Space industry with hard to obtain technology Attitude Control Systems Rocket Engines Rocket Propellants Test Facilities

Attitude Control Systems: 

Attitude Control Systems Attitude Control Systems (“Guidance Systems”) Classical vs. State Space design Classical Typically considers each axis independently (single input, single output or SISO), cross coupling is fudged Uses “Transfer Functions”; no modeling of internal physics Uses relatively simple control laws (integrals and derivatives) State Space Originally developed by Soviet space program Correctly models multiple input multiple output (MIMO) systems Models system physics using a set of simultaneous differential equations (can be linear and non-linear) Control law solutions are inherently coupled and model the entire system more accurately

State Space vs. Classical ACS: 

State Space vs. Classical ACS Boeing Delta 2 ACS was modified for Delta 3 Notice the similarities of the two launch vehicles. Boeing felt that they could modify the Delta 2 guidance system to work on the Delta 3

State Space vs. Classical ACS: 

The Result: State Space vs. Classical ACS A roll oscillation mode, never before the primary oscillation mode for the Delta 2, became the primary oscillation mode for the Delta 3 due to the larger strap on solid rockets Guidance system misinterpreted this oscillation as a disturbance, and expended all of its hydraulic fluid trying to fight it This could not have happened if a State Space model were used as the simultaneous differential equation modeling of the kinematics of the vehicle would automatically take this into account (Disclaimer: I have never worked for Boeing, but the explanation of the failure belies the problem) A very similar failure occurred when Arianespace used a modified Ariane 4 control system on an Ariane 5

Slide7: 

Attitude Control Systems We can provide complete Attitude Control Systems for your prototype vehicle Inertial guidance GPS State Space theory, full state feedback design State Estimator design Attitude Control Systems

Masten XA-0.1 ACS: 

Masten XA-0.1 ACS Pilot will command vehicle rates to the ACS GPS data used to correct IMU for drift GPS also used to guide pilot to target To be flown for the Lunar Lander Challenge Masten XA-0.1 is the prototype for their suborbital space vehicle

Masten XA-0.1 ACS: 

Masten XA-0.1 ACS Masten XA-0.1 has four engines located on the circumference of the base System to be controlled

Masten XA-0.1 ACS: 

Masten XA-0.1 ACS g F Fz Fx g Md Mh Md: Moment due to differential thrust Mh: Moment due to hinge angle Md = Mh Engines are individually throttled and hinged Fx Frontier Astronautics’ design allows an ACS to accelerate the vehicle laterally without tipping the vehicle This “Crabbing” maneuver helps landing on rough terrain as well as terminal landing accuracy

SpeedUp ACS: 

SpeedUp ACS SpeedUp Lunar Lander Challenge vehicle “Laramie Rose” Prototype vehicle to prove concept of SpeedUp’s “Flying Motorcycle”

SpeedUp ACS: 

SpeedUp ACS Lateral flight for “Laramie Rose” Frontier Astronautics’ design allows for accurate landing on a pre-determined location Hands-off flight Three control vanes g F Fz Fx Acceleration Constant Velocity Deceleration Stationary Hover Over Landing Pad Landing location is known so ACS can initiate brake at the correct time F F nozzle vane

Rocket Engines: 

Rocket Engines Viper™ engine Pressure fed LOX/Kerosene 7500 lbf thrust Designed to be clustered for 30,000 lbf Removable inexpensive ablative liner Low injector pressure drop allows lighter flight system (tanks)

Viper™ Engine: 

Viper™ Engine

Viper™ Engine: 

Viper™ Engine Modular design for ease of maintenance Ablative nozzle designed to be replaced in minutes for fast turn around flights Patent Office notice of publication granted, to be published 4/12/07 We are willing to license this technology

Viper™ Engine: 

Viper™ Engine Injector designed for stable combustion despite having a low pressure drop across the injector face This allows the use of a pressure fed system (no turbo pump) without heavy propellant tanks

Viper™ Engine: 

Viper™ Engine General Concept: Dimension injector for harmonics to destructively interfere Combustion instability is mitigated without the need to have a large injector pressure drop

Viper™ Engine: 

Viper™ Engine Helmholtz resonators located around periphery of injector face The resonators damp the tangential, longitudinal and radial primary frequencies Used on Shuttle OMS engines Spintle™ is also dimensioned to damp the tangential, longitudinal and radial primary frequencies Fuel and oxidizer is injected to mix at the half-integer of the primary wavelength as well This results in combustion oscillations being damped before they have a chance to amplify and affect the engine

Rocket Engines: 

Rocket Engines Asp™: engine Pressure fed hydrogen peroxide 1500 lbf thrust Uses a dual catalyst for rapid warm up Does not need the catalyst pack to be loaded under pressure by hydraulic press; lowers servicing requirements Design reduces hydrogen peroxide blow-by (wasted energy) Throttle Range: 300 lbf to 1500 lbf

Asp™ Engine: 

Asp™ Engine Frontier Astronautics designed, built and tested the Asp™ Rocket Engine for SpeedUp 80% - 99% Hydrogen Peroxide Catalyst pack does not require compression loading Design reduces hydrogen peroxide blow-by (wasted energy) Throttle Range: 300 lbf to 1500 lbf -insert picture here-
