Hypersonic Interceptor Aerodynamics

Hypersonic Interceptor Aerodynamics

Objective: Development and testing of a multi-stage, hypersonic, hit-to-kill missile designed to intercept an exoatmospheric target

Summary: This was a multiple task effort consisting of (1) 6-DOF aerodynamics model generation, (2) payload compartmental venting system development, (3) debris dispersion footprint estimation, and (4) flight test performance validation. The 6-DOF aero model required consideration of nine (9) distinct vehicle configurations that accrued between launch and target intercept. Development of the compartmental venting system was required due to outgassing of the missile payload within a confined internal volume. Parametric analysis of the time-variant venting process resulted in specification of the number, external location, and type of vent devices. Predicted venting performance agreed closely with flight test venting measurements. Multiple flight tests of the hypersonic interceptor were conducted with all missile debris falling within the 3Σ dispersion footprint. Flight extracted aerodynamic forces and moments agreed well with predictions based on the 6-DOF aerodynamics model.

080605-N-0000X-001Missile IR Seeker Cover Jettison

Objective: Establish the safe separation envelope for an aerodynamic cover protecting a missile side-mounted IR seeker in supersonic flight

Summary: A multiple degree-of-freedom jettison simulation was developed and employed to conduct safe separation studies of the subject cover. The aerodynamics model for the wedge-shaped device was generated using engineering methods while the missile shock layer flowfield model was generated using Euler-based computational fluid dynamics. A comprehensive Monte Carlo analysis that considered 3Σ uncertainties in aerodynamics, flowfield properties, cover release actuator output, cover release conditions, and atmospheric properties provided the required safe separation envelope as functions of Mach number, altitude, and missile total angle-of-attack and aerodynamic roll position. Cover separation time histories generated by the jettison simulation matched very well with those experimentally-determined in the wind tunnel as well as full-scale sled track testing.

Hypersonic Aircraft Flush Airdata Sensing SystemHypersonic Aircraft Flush Airdata Sensing System

Objective: Design, develop, and test a Flush Airdata System (FADS) for the HYPER-X Research Vehicle (HXRV) also known as the X-43A

Summary: A 9-port FADS layout was devised to provide inflight airdata consisting of Mach number, dynamic pressure, angle-of-attack, angle-of-sideslip at hypersonic speeds. Implementation included use of a suite of precision pressure transducers connected to individual pressure orifices via small-diameter, long-flow-path pneumatic tubing. The combination of long internal flow paths and the low ambient pressures associated with high altitude flight required compensation for the effects of pneumatic lag, internal flow wave-induced spectral distortion, and internal flow thermal transpiration on the sensed pressure signal. Ground testing using a 80%-scale forebody model and full-scale pressure transducers and plumbing was conducted at Mach numbers between 2 and 8. The X-43A FADS system was successfully flown and operated at flight Mach numbers up to 10.

Access to SpaceAccess To Space

Objective: Perform a conceptual design and analysis of launch vehicle and reentry vehicle systems intended for manned commercial access to space

Summary: Major tasks included multi-stage launch vehicle configuration synthesis, aerodynamics model generation, and optimization of the ascent trajectory into orbit. The spacecraft attitude control system was sized to provide 3-axis flight control both on-orbit and during reentry. Continuum and rarefied flow aerodynamic models were generated and implemented in performing flight simulations of the reentry vehicle trajectory following activation of the deorbit propulsion system. A major aspect of the work involved minimizing the reentry vehicle thermal protection system mass and yet select a material that allowed the heatshield to be reused over multiple missions.

Missile Debris Dispersion FootprintMissile Debris Dispersion Footprint

Objective: Devise, develop, and validate an analytically-based system for estimating the 3Σ dispersion footprint for debris elements resulting from in-flight destruction of a missile airframe

Summary: A debris dispersion footprint was required as part of the process to gain range safety approval for flight at major missile test installations. Missile debris included randomly tumbling, low and high ballistic coefficient elements resulting from activation of the flight termination system via either a command destruct or self-destruct. Key work focused on (1) defining the types of debris that result from missile detonation, (2) formulation of creditable missile failure scenarios, (3) development of representative ballistic coefficient models for various types of missile debris, and (4) development of a multiple degree-of-freedom flight simulation. Upon completion, the overall debris dispersion footprint estimation system was validated using previous flight test results and subsequently became a key component of obtaining safety approval for the conduct of numerous missile flight tests over a period of 15 years.

Hypersonic Airbreathing Vehicle Flight TestHypersonic Airbreathing Vehicle Flight Test

Objective: Obtain aerodynamic flight research measurements during hypersonic flight of the X-43A airframe-integrated scramjet test vehicle

Summary: This was a multiple task effort requiring (1) layout of a flight test instrumentation system, (2) acquiring surface pressure and temperature data , and (3) extraction of vehicle aerodynamic forces and moments from flight motions. A suite of pressure orifices and thermocouples was devised for making local aerodynamic measurements at over 300 locations on the vehicle surface. The type, range, sensitivity, and data acquisition rate were specified for each of these sensors. The development and installation of the instrumentation system was controlled via a rigorous configuration management system. The flight research measurements obtained from hypersonic flights of the X-4A to Mach 7 and Mach 10 were of unprecedented quantity and quality. Using a combination of the Best Estimated Trajectory (BET), Inertial Navigation System (INS) accelerometer and rate gyro measurements, control surface deflection-time histories, 3-space mass properties, and the Body Axis 6-DOF equations of motion, the vehicle 6-DOF aerodynamic forces and moments were successfully extracted throughout the descent flight profile of each mission.
