C-130 SERIES AIRCRAFT ENHANCEMENTS AND MODIFICATIONS
As the world has come to realize the Lockheed C-130 is the major aircraft type that can operate worldwide in any weather or physical conditions. Snow Aviation LLC International (SAI) has prepared their C-130 series of standard and optional modifications to allow the aircraft to fly safely and meet the conditions being demanded by the circumstances facing their operators worldwide today. Many potential customers cannot afford the cost of new versions of the C-130J aircraft series which are running well in excess of $97 million each to solve the requirement to replace wing components that are running out of time, old avionics, electrical equipment, mission systems updates, etc. on the older C-130 models. Removal of this older C-130 installed equipment is being demanded as the safety upgrades on these older aircraft by the countries that are experiencing tremendous flight increases on their flight control agencies and the added mission requirements to meet the potential customers military operational demands of today. The C-130 Series of Aircraft need to be able to fly at slower speeds and work with requirements based on minimum developed runways, mountainous terrain and other demanding situations that the current terrorist’s look for their training and continuing operations areas to penetrate a country. Many of these SAI modifications listed herein have been successfully demonstrated to the US Government during a series of demonstration contracts flown by SAI under military contracts from 2005 to 2007. The following listings describe the proposed C-130 modifications SAI intends to offer for the 850+ C-130B/E/H Series aircraft not being serviced by Lockheed today, but still needed by these older aircraft in over 70 countries worldwide today. Not all of these SAI offerings will be bought by every potential customer, however, over 450 of these customers are considered as being prime for selecting most of the items listed below as their C-130s are still the aircraft relied upon to perform the required operations against the current terrorist and insurgent situations and natural disasters being demanded of them worldwide

SAI Installation of an Auxiliary Power Unit (APU) and Removal of the Older C-130 GTC/ATM Components
The current Gas Turbine Compressor (GTC) installation in the earlier C-130/L-100 aircraft supplies the compressed bleed air to power the AIR Turbine Motor (ATM) which in turn powers the DC electrical generator in the upper fuselage portion of the center wing which supplies electrical power while the aircraft is on the ground without the aircraft’s engines running.

SAI Dual Battery Installation
SAI has developed and flown a dual battery installation for the C-130 that meets the current US Federal Aviation Administration (FAA) and US Military Electrical Power/Emergency Service Time Requirements in case of a complete power generation failure on an aircraft

SAI Electrical Control and Distribution System
SAI has also designed, produced, ground and flight tested a new electrical control and distribution system that has also been issued a US FAA Supplemental Type Certificate (STC) for this new system on a C-130/L-100. In addition, the USAF has issued a Technical Order (TO) 704E that requires all of their aircraft to meet the provisions for proper power levels and power stability for the new aircraft and support system requirements for retro equipment still in use on the older aircraft.

ABS Dorsal Fin HF Antenna Mount Installation
This installation removes the two long line HF antenna wires from the front top of the aircraft thus reducing the aerodynamic drag on the aircraft by approximately 3% while improving the HF transmission and reception capabilities and significantly lowering of the associated system maintenance requirements.

SAI Enlarged Dorsal Fin
The SAI enlarged dorsal fin was designed, built and installed by SAI and then flight tested under contract with the USAF on our prototype C-130E.

SAI Enlarged Rudder
The SAI enlarged rudder was designed, built and installed by SAI and then flight tested under contract with the USAF on our prototype C-130E.

SAI Wing Tip Fuel Tanks and Associated Outer Wing AND Fuel System Modifications
The new SAI Wing Tip Fuel Tanks installation were designed, built and installed by SAI and then flight tested under contract with the USAF on the SAI C-130E prototype aircraft.

SAI Aft Fuselage Strakes
SAI also has designed a set of C-130 Aft Fuselage Strakes that they will build and flight test with installation on their demonstration aircraft. Aft fuselage strakes have previously been installed on a C-130 fuselage and they did reduce aft fuselage drag and provide a contribution to the airframe’s stability at slow airspeeds.

UTC Carbon Brakes and Lock Ring Wheels
The UTC carbon brakes, and lock ring wheels allow a minimum of 8 times as many braking operations as the current multiple steel disk brakes before they need to be changed. The lock ring wheels allow a tire change in 28 minutes versus 23 hours for a similar tire change on a standard C-130/L-100 tire and wheel installation.

SAI Glass Cockpit Modification Installation
SAI has improved its original glass cockpit over the last 17 years since we installed it in our company’s C-130A Testbed Aircraft.

Engine Upgrades
SAI can accomplish engine upgrades for replacement of the earlier T56-A-7A/B series engines with the more powerful T56-A-15 or LFE version of the T56-A Series engines. The T56-A-15 series engines offer Shorter Airfield Take-off and Landing and faster climb and cruise airspeed capabilities for the earlier C-130B/E Models.

RR-Allison Engine Upgrades to the T56-A-15, Series 3.5 Standard
SAI believes that the T56-A-15, Series 3.5 is the most efficient means for the early C-130B/E/H operators to gain additional power, capability and reliability for their aircraft to meet their growing market demands. SAI believes that the installation of the T56-A-15, Series 3.5 on the older C-130 plus installation of the appropriate SAI Modification Programs for their missions will give these operators the best return of economy and reliable productivity they can have from their C-130s.

SAI Nacelle and Associated Nacelle Structures
SAI has designed and analyzed new forward and aft engine nacelle components to reduce the stress concentrations between the current engine mount and the front spar of the wing. SAI’s analysis shows a loads concentration reduction of approximately 50% for this mounting area utilizing the new SAI engine mounts, QEC and aft engine nacelle designs.

Hamilton Sundstrand 8 Bladed NP2000 Composite Propellers and Electronic Propeller Control
SAI was the first company to install the Hamilton Sundstrand NP2000 8 bladed composite propellers on its C-130E test aircraft in 2006. The NP2000 propellers increased the thrust at the start of the takeoff roll by 28% while still producing 12% increase in thrust at aircraft lift off during takeoff.

SAI install C-130H Nose Gear and Installation Package
The C-130H component and mounting structure can be overhauled, tested and installed in 30 days. The SAI nose gear installation of the C-130H Nose Gear Mounting Structure and Nose Gear Component is superior or earlier variants.

New Cockpit Seats
The seats are smaller, lighter and much more comfortable than the traditional C-130 cockpit seats. The seats have over 30 adjustments and provide a very comfortable and functional seating arrangement. The seats mount in the traditional cockpit seat rails and allow much more free space in the immediate area of the cockpit seats than with the standard C-130 cockpit seats.

C-130 Airframe Overhaul
Because of the amount of update and modification work being accomplished on this aircraft it makes an overhaul of the airframe a very economical operation if accomplished along with the other referenced work being accomplished.

Electrical Cockpit Air Conditioning
SAI designed the installation kit and installed the original smaller Electrical Cockpit Air Conditioning unit from their selected sub-contract manufacturer in our prototype demonstration C-130A aircraft and it cooled our cockpit on a 104-degree day at Eglin AFB to 70 degrees and kept it there while the aircraft was on the ground and the unit running on power from a ground aircraft power unit. This air-conditioning unit is electrically powered and can be run from a ground power unit or the aircraft’s electrical system while airborne.

SAI Newly Developed Cargo Handling System
SAI has designed and engineered a new cargo handling system for the C-130 and L-100 series of sircraft. The system features fold down outer locking system rails that can be rapidly folded down or moved up to provide maximum width for loading wheeled equipment or placed up to horizontally and vertically stabilize the outboard portions of pallets/containers.

A New Sub-Cargo Floor Mounting Winch System
SAI is aware of the standard times it takes with the older C-130s for an aircrew to unload and reload their aircraft with different types of loads while supporting their military missions in the field. Positioning a winch and attached cables on top of the cargo floor to be moved by the loading crew assists the loading of a heavy load which is tiring and time consuming with a 300-pound winch.

Aircraft Cockpit Galley
Aircraft galleys with the plan to upgrade the C-130 cockpit of the older C-130 series aircraft with a new galley utilizing new solid state and state of the art components. The proposed unit will be lighter, require considerably less power, operate at temperatures on the outside of the galley components installation that are cooler than the current C-130 galley units, have more capacity and require significantly less maintenance.

SAI Horsals
SAI has designed, will build and test the new aft fuselage horsals for the C-130 as soon as a customer requests them, or a decision is made by SAI to include them on their demonstration aircraft.

SAI’s C-130E/H – L-100 Fuselage Stretch
The C-130 and L-100 fuselage stretch engineering was initiated by the commercial L-100 operators to increase their cargo cubic payloads.

C-130 Lightning Protection System
SAI has designed a new lightning dissipation system for the C-130. The system concentrates on lightning hits on the nose, wing tips and vertical fin areas of the aircraft.
 
SAI Trailing Arm Nose and Main Landing Gear
SAI originally designed its trailing arm landing gear components for its SA-200 series aircraft design which was subsequently modified to withstand the added physical loads associated with the heaviest C-130s currently in use or as demonstrated by the SAI prototype aircraft to the USAF under contract.

C-130 Wing Work
A real concern for many of the older C-130 operators is the total time on their aircraft’s center wings. If the center wing is out of time or approaching major restrictions on its operation the time to address the problem is when SAI is doing all the work described in a proposal. SAI only replaces center wings with the heavy weight USAF center wing components or a rebuild of the center wing to the same heavy weight specifications.
