Do not cite this document as a requirement. AMSC: N/A AREA SESS DISTRIBUTION STATEMENT A. Approved for public release; distribution is unlimited. Downloaded from http://www.everyspec.com MIL-HDBK-1760A FOREWORD 1. This handbook was developed by a team including members from the three U.S. military services, the UK MOD, the SAE AS-1B committee, and contractors. It includes information previously published in document ASD-TR-87-5028 with certain elements of ASD-TR-91-5009. Some of this information was also published in DEF-STAN-00-69 (Part II), which is written around MIL-STD-1760B. This revision of this handbook is written around MIL-STD-1760D and assumes that the reader is also reading 1760D. 2. This handbook provides information on the implementation of a standardized electrical interconnection system, as defined by MIL-STD-1760, into both current and future aircraft and stores. It provides guidance on design considerations and options for including the standard interface capability at the aircraft's store stations and for providing a common electrical interface on carriage stores and mission stores. As a handbook, it cannot be invoked as a requirement in a contract. 3. Trends in weapon system designs (aircraft and stores) caused concern over the general proliferation of aircraft-to-store electrical interfacing requirements and the resulting high cost to achieve interoperability between aircraft and stores. -

Abstract The desire for a vertical takeoff and landing (VTOL) aircraft capable of high forward flight speeds is very strong. Compound lift-offset coaxial helicopter designs have been proposed and have demonstrated the ability to fulfill this desire. However, with high forward speeds, noise is an important concern that has yet to be thoroughly addressed with this rotorcraft configuration. This work utilizes a coupling between the Rotorcraft Comprehensive Analysis System (RCAS) and PSU-WOPWOP, to computationally explore the acoustics of a lift-offset coaxial rotor sys- tem. Specifically, unique characteristics of lift-offset coaxial rotor system noise are identified, and design features and trim settings specific to a compound lift-offset coaxial helicopter are considered for noise reduction. At some observer locations, there is constructive interference of the coaxial acoustic pressure pulses, such that the two signals add completely. The locations of these constructive interferences can be altered by modifying the upper-lower rotor blade phasing, providing an overall acoustic benefit. -

When responding to wildfires, the helicopter can quickly deliver up to a 9-person Helitack Crew for ground firefighting operations and quickly transition into water/foam dropping missions. The helicopters are also used for firing operations using either a Helitorch or a Chemical Ignition Device System (CIDS) on wildland fires or prescribed burns, transporting internal cargo loads, mapping, medical evacuations and numerous non-fire emergency missions. The CAL FIRE HAWK is also equipped with an external hoist for rescue missions. -
S-70 Firehawk® Multi-Role Helicopter
™ ® S-70 Firehawk Multi-role Helicopter Colorado Backgrounder In Southern California, a Sikorsky S-70 Firehawk helicopter flies low to drop water on a small wildland fire. The aircraft’s ability to reach remote fires quickly — often before ground firefighters arrive — can prevent a small blaze from spreading out of control. The state of Colorado is looking to acquire several multirole Firehawk aircraft for both firefighting and year-round search and rescue. Background: Governor Jared Polis has added to the proposed budget for 2021-2022 fiscal year an S-70 Firehawk helicopter as a permanent state-owned asset to fight wildfires. The $23.9 The case to own million cost of the aircraft with associated equipment and training is part of a $78 million firefighting assets package for wildfire relief, mitigation and prevention.

Since then, the cold war ended and a global war on terrorism began. These developments have led to far-reaching Ichanges in the way we fight and procure weapons. They have necessitated a rethinking of how we organize and structure our military forces, how we man and train them realistically to face these new threats, and how we equip them in a timely and effective manner with the best systems that rapidly advancing technologies can offer. In support of these objectives, DoD has undertaken a major transformation of its acquisition process, codifying the latest changes in May 2003. In parallel, significant changes in the regulation governing requirements generation eliminated the term “requirement” in all the documentation, and replaced it with “capability” for new weapons programs. These innovations have not altered the core mission of DOT&E. This is largely attributable to the original legislation being so clear, focused, and close to the core mission of the acquisition system. Our maxim remains one of determining whether systems will be effective, suitable and survivable in combat, and providing that information to decision makers before commitment to full-rate production or deployment with our combat forces. -
