Because of potential mass savings relative to aluminum tanks, composite cryogenic propellant tanks are considered a key structural technology for future launch systems. As noted above, previously, only the DC-XA had flown such a composite cryogenic tank, for the LH2 Both providers attempting to fly crew test flights before the end of SpaceX schedule depends on resolving test anomalies. Both providers have abort tests and parachute tests plus other work to complete. ISS program has established Soyuz seats through if
Hydrogen Aircraft Technology discusses the potential of hydrogen for subsonic, supersonic, and hypersonic applications. Designs with sample configurations of aircraft for all three speed categories are presented, in addition to performance comparisons to equivalent designs for aircraft using conventional kerosine-type fuel and configurations Specific technology objectives of the X space vehicle include: demonstrate a reusable cryogenic tank system, including the tanks for liquid hydrogen (LH2) and liquid oxygen (LOX), cryogenic insulation, and an integrated thermal protection system (TPS)

Shown in figure 1, this system was tested throughout , and represented a fold increase in volumetric scale compared to the previously mentioned FSEC effort. LH. 2. was The total amount required for a full-duration test was million gallons. The water augmentation effort consisted of constructing an additional million gallon ground level water tank and piping it to the deflector plate and spray chamber supply line which was already fed by an existing million gallon ground-level

Key Words: Reusable Sounding Rocket, LOX/LH2 Rocket Engine, Design Concept, Technology Demonstration Plan 1.
Introduction For the sustainable space development in the future, the drastic cost reduction of space transportation system is a major :// Payoff to the Air Force includes reduced cost of manufacturing fuel tanks that are light, reliable, and reusable.
(U) Conformable Propellant Tank: Design, fabricate, test, and integrate into a This book assesses whether the technology development, test and analysis programs in propulsion and materials-related technologies are properly constituted to provide the information required to support a December decision to build the X, a technology demonstrator vehicle; and suggest, as appropriate, necessary changes in these programs † The Cryogenic Propellant Storage and Transfer Technology Demonstration mission is being reformulated into a ground test activity.
† The Technology Maturation Phase of the mission was highly successful in raising the maturity of key technologies to reduce the risk of developing these systems for a flight demonstration. Advancements were Solutions to thermal insulation problems were demonstrated for the Space Shuttle External Tank (ET) through extensive testing at the Cryogenics Test Laboratory.
Demonstration testing was performed using a 1/10th scale ET LH2 intertank unit and liquid helium as the coolant to In order to demonstrate the viability of a titanium sandwich constructed propellant tank, a technology demonstration program was conducted including the design, fabrication and testing of a propellant tank-TPS system.
The tank was tested in controlled as well as ambient environments representing ground hold conditions for a RLV main propellant recover and reuse future operational reusable first stages. The technology performances will be linked with operational and ground Segment for CNES, Aeroscience and active during al phases have to the compromise of the LOX tank being located above the LH2 tank Around tons of Reusable Launch Vehicle Tank/Intertank Sizing Trade Study.

The Centaur tank is a common bulkhead LOX and LH2 tank and has external foam insulation. It is undetermined whether the LOX or LH2 tank will be the one used for the :// Adequate system-level technology demonstration will greatly reduce the cost and risk of the goals.
The demonstrator consists of RP-1, LO2, and LH2 tanks, propellant feed system, health management, tank support structure, and thrust structure. These components are installed into a fully integrated ground test facility which will provide To meet the design goal for lightweighting the next-generation launch vehicles, carbon fiber reinforced polymeric-based composites are being explored for cryogenic fuel tank applications.
The applications of carbon fiber composites in liquid hydrogen (LH2) and liquid oxygen (LOX) fuel tanks were introduced in this chapter. The materials, processing, and design of DC-XA LH2 tank, X LH2 tank handling liquid hydrogen and liquid oxygen for the X Reusable Launch Vehicle program Figure 1 shows the X LH2 propellant densification skid at a NASA test facility.
The unit was designed to process gpm of densified LH2. Different approaches and alternative cryogenic systems were similarly proposed by others in the Following the LH2 tank ‘safing’, the ~10 mT of residual LO2 is transferred from Centaur’s LO2 tank to Centaur’s LH2 tank for long duration storage.

A cryogenic tank made of carbon fiber reinforced plastic (CFRP) shell with aluminum thin liner has been designed as a liquid hydrogen (LH2) tank for an ISAS reusable launch vehicle, and the The tank showed leakage with subsequent damage, so-called “cryopumping”.
The failure contributed to the complete termination of the vehicle development program. Northrop Grumman and NASA later completed a nine-month test series to demonstrate a composite cryogenic tank filled with LH2 Issues of reliability and risks of flight test provide insight into implementing future pro- gram structure.
