Design
The CH-148 has a metal and composite airframe. The four-bladed articulated composite main rotor blade is wider and has a longer radius than the S-70 Blackhawk. The tapered blade tip sweeps back and angles downward to reduce noise and increase lift. Tethered hover flight has recorded 138 kN (31,000 lbf) of lift generated, both in and out of hover effect.
A number of safety features such as flaw tolerance, bird strike capability and engine burst containment have been incorporated into the design. An active vibration system ensures comfortable flight and acoustic levels are well below certification requirements. The Cyclone will feature a modified main gearbox, which has been redesigned since a March 2009 accident.
The CH-148 is equipped with devices to search and locate submarines during ASW, and is equipped with countermeasures to protect itself against missile strikes. The Integrated Mission System is being developed by General Dynamics Canada, as is the Sonobuoy Acoustic Processing System. The radar is a Telephonics APS-143B, the EO System a Flir Systems SAFIRE III, the sonar an L-3 HELRAS, and the ESM a Lockheed Martin AN/ALQ-210. CMC Electronics provides the flight management system, named CMA-2082MH Aircraft Management System.
Unlike the CH-124, the Cyclone is not an Amphibious helicopter and can only float on the water for a short time.

Famous quotes containing the word design:
“If I commit suicide, it will not be to destroy myself but to put myself back together again. Suicide will be for me only one means of violently reconquering myself, of brutally invading my being, of anticipating the unpredictable approaches of God. By suicide, I reintroduce my design in nature, I shall for the first time give things the shape of my will.”
—Antonin Artaud (1896–1948)
“To nourish children and raise them against odds is in any time, any place, more valuable than to fix bolts in cars or design nuclear weapons.”
—Marilyn French (20th century)
“If I knew for a certainty that a man was coming to my house with the conscious design of doing me good, I should run for my life ... for fear that I should get some of his good done to me,—some of its virus mingled with my blood.”
—Henry David Thoreau (1817–1862)
